many of the ingredients of the media of this invention have an impact , some being glucose , pyruvates and lactates , fats , vitamins , proteins and antioxidents , amino acid concentrations are also needed in order to provide for the synthetic requirement of cellular repair . when the time comes to be revived or unfrozen , the specimen is then removed from the liquid nitrogen container and placed into a series of thawing media for a specific time intervals and through several steps . the method and system of this invention will provide pre - vitrification , thawing and post thawing embryos a balance of ingredients that will provide the embryo with those ingredients which will allow it to better recover from a metabolic shift and inner mitochondrial membrane damage caused by the cp process . when the specimens are being prepared for cryopreservation the specimens are handled in several different methods and different ingredients , depending on the selected protocols and products . the subject technology will increase the chances of increased pregnancies and live child birth in the embryos cultured in the solution as opposed to the other solutions . the subject technology will increase the chances of stem cells recovering and becoming more useful as well a greater survival rate . some of the combinations will include ingredients such as stabilizers or antifreeze proteins which may help recovery and development . the subject disclosure may include energy sources such as fructose , glucose , maltose , mannitol , sorbitol , sucrose and trehalose . additional ingredients such as , vitamins fats , globulin and antioxidents are included . the subject disclosure has also altered the volume of calcium , magnesium and phosphate to help support development . referring now to the drawings , fig1 compares current methods of thawing or devitrifying specimens with an embodiment of the invention and its methods for thawing and devitrifying . it further describes the current methods for the thawing and use of the specimens , compared to the new method . in this example embryos are used as the specimen , the methods of thawing them , placing them in media solutions until they are ready for transfer and then the transfer step . it will be appreciated that embryos , stem cells and oocytes can be treated in a similar manner by using the resucitation solution of this invention . current methods may use from 2 to 7 vials in the thawing process , and may vary in the times . for this example we are describing a method using 4 thawing steps and 4 separate solutions the specimens remain in each solution . in this example the fourth vial is considered the last step . in this example the frozen embryos are removed from the liquid nitrogen tank 10 and placed into the first thawing solution 14 . current media will consist of a base media solution , which will include from 0 . 5 - 0 . 8 mm of sucrose and 10 - 12 mg / ml of human serum albumin ( hsa ) and may contain 1 , 2 propandiol or similar cryoprotectorants . the ingredients may vary , but are fairly consistent through the many manufacturers . the embryo remains in the first solution 14 for approximately 5 minutes . the embryo is then transferred to vial # 2 18 for 5 minutes . vial # 2 18 may contain a base media , from 0 . 2 - 0 . 5 mm of sucrose and hsa and may contain 1 , 2 propandiol or similar cryoprotectorants . the embryo is then moved into the vial # 3 solution 22 for approximately 10 minutes . vial # 3 22 may contain a base media , from 0 . 1 - 0 . 2 mm of sucrose and hsa . the embryo is then moved to a generic media 32 , for several hours and then transferred into the patient . in this example “ generic media ” refers to a media that is used for un - frozen specimens and is not differentiated for frozen specimens . the embryos are then moved from the generic media 32 and transferred into the patient 34 . in practicing the method of this invention , the user may use the current methods of moving the embryos through the 1st solution 14 , second solution 18 and the 3rd solution 22 . the embryos are removed from the # 3 thawing solution 22 and at step 24 moved to the rejuvenating solution 60 of this invention . the solution 60 is a solution which addresses the needs of embryos that were frozen and are being thawed to be later implanted , and addresses the fact that the frozen embryos have different nutritional needs than fresh embryos . in method a the embryos are moved at 24 into the solution 60 before they are put into the last thawing solution 30 . this exposes the embryos to the enhancements of the solution 60 , due in part to the fact that most last thawing solution are only a base media solution and hsa ( human serum albumin ). therefore it is more beneficial to be in the solution 60 than in the last solution 26 . this example also allows the solution 60 to become the final solution used in the sequence of solutions and the last solution in kits currently provided by ivf companies . in method a , the embryos are held in the solution 60 for a period of time , undefined in this example , and then may be moved in step 64 to a “ generic medium ” 72 for a predetermined period of time . the embryos are then transferred to the patient 74 from the generic medium 72 . this allows users to use any of a number of generic media that they may be more accustomed to before they transfer the embryo . the embryo is then moved from 72 and transferred into the patient 74 . alternatively in method a , the embryos may be held in the solution 60 until they are transferred into the patient 76 , through step 68 . therefore this embodiment is a unique combination of steps and is used in the thawing and recovery process of the embryos as well as used for the growth and culturing of the embryos through to the transfer stage 74 . in method b , the embryos are placed in the method b last solution 30 , then at step 28 are moved to the rejuvenation solution 80 . the move to the solution 80 , in this example , allows the user to utilize the steps or protocols of the current method , which are steps or protocols they may prefer , or be more accustomed to using . after the embryos are moved to the solution 80 , they may be cultured in the solution 80 ( step 84 ) until they are transferred into the patient 96 . the user may choose to move the embryos in step 88 to a generic medium 92 , for a time period , a step which they may be more accustomed to , and then the embryos can be implanted into the patient 96 . in this example the media solutions of 32 , 72 and 92 may be generic medium , may be a “ transfer ” medium , or may be a combination of both . transfer medium , in this example , is a medium designed for the step of transferring the embryo to the patient and may include additional ingredients , such as hyaluronic acid . this example demonstrates the unique nature of the rejuvenation solution , and its added specific ingredients and the old methods a and b , for the handling of the embryos and the introduction or addition of the rejuvenation solution into the older current methods and protocols . referring now to fig2 , there is shown a similar procedure for freezing or vitrifying specimens such as embryos , stem cells or oocytes . in the prior art method , the specimens , such as embryos or oocytes to be cryopreserved by freezing or vitrification are cultured in a culturing media 200 . this occurs in an incubator environment . the embryos are selected for cryopreservation and then put through the vitrification or freezing process in specific cryoprotectorant ( cp ) media solutions 202 . typically in the first vitrification step , the media will include two cyroprotectorants which will each provide 7 . 5 % of the first step medium . then in the second vitrification step , the cryoprotectorants will each provide 15 % of the second step medium . after they have been thus prepared for vitrification in the are then moved to storage in a liquid nitrogen tank 204 . the specimens will remain in the tank 204 until needed to be thawed and used . the method of this invention includes a specially designed media in the sequence to provide the embryos with much needed components before they enter the vitrification process . the embryos are cultured in an embryo culture media 220 , before cryopreservation . the embryos are moved from the generic culture medium into a preparation / rejuvenation medium 225 a which contains the combination of ingredients , described above and is devoid of hepes or mops . this special solution contains additional ingredients useful in preparing the specimen for cryopreservation . the embryos are then moved into a second preparation / rejuvenation medium 225 b which does contain hepes or mops . including hepes or mops , a bicarbonate , allows the embryos to be handled outside the incubator environment , and including hepes or mops allows the user to prepare the embryos inside of the incubator environment for a longer period of time . the embryos are then placed in the sequential vitrification solutions 230 and 231 , and then stored in liquid nitrogen tank 275 . referring now to the tables , table 1 shows the changes made to a basic media formulation a . this table shows what is a generic medium solution that has been successful in developing embryos through to the cleavage and blastocyst stage of development . this table shows the majority of ingredients used in this proven medium . the combination of pyruvates , glucose and lactate in the rejuvenation solution will outperform the conventional media in the post thawing process . added to the proven media formulations are varying amounts of fatty acids , vitamins , antioxidents and globulins . the term “ amino acid ” as used herein , refers to amino acids or their derivatives . examples of such amino acids include l - alamine , glycine , l - alanine , l - arginine hcl , l - asparagine , l - cysteine , l - aspartic acid , l - glutamic acid , glycyl - glutamine , l - phenylalanine , l - histidine , l - isoleucine , l - lysine hcl , l - leucine , l - proline , l - serine , l - threonine , l - tryptophan , l - tyrosine , and l - valine . in modifying the basic medium ingredients , glucose is increased ten fold from 0 . 036 to 0 . 18 g / l . lactate is decreased from 1 . 12 to 0 . 56 gg / l . pyruvate is increased from 0 . 022 to 0 . 030 g / l . the levels may vary slightly and acceptable levels of glucose may be from 0 . 20 to 0 . 40 g / l ; lactate may vary from 0 . 20 to 1 . 20 g / l ; and pyruvates may vary from 0 . 005 to 0 . 030 g / l . the medium of this invention includes the addition of fatty acids , lipioc acid in a concentration of from 0 . 000004 to 0 . 0000012 g / l , with a preferred amount of 0 . 000008 g / l ; and linoleic acid in a concentration of from 0 . 000002 to 0 . 000008 , with a preferred amount of 0 . 00005 g / l . the fatty acids may be supplemented with similar performance fatty acids . the invention includes the addition of vitamins , alpha tocopheral acetate in a concentration of from 0 . 00025 to 0 . 00075 g / l , with a preferred embodiment of 0 . 0005 g / l , ascorbic acid phosphate in a concentration of from 0 . 001 to 0 . 01 , with a preferred amount of 0 . 0025 g / l . menadione k3 in a concentration of from 0 . 00005 to 0 . 0005 , with a preferred amount of 0 . 0001 g / l . vitamin k2 in a concentration of from 0 . 00005 to 0 . 0005 , with a preferred amount of 0 . 0001 g / l ; globulin may be added separately or in a subcomponent such as has and globulin . the vitamins may be supplemented with similar performance vitamins . table 2 compares some of the media considered in the prior art example of fig1 . table 2 shows the more common “ generic ” media solutions in the marketplace and their published concentration of the ingredients glucose , sodium and sodium lactate . this includes those common in embryo development and culturing . table 2 shows that p1 , a common culture medium , which would be used as the generic medium of fig1 , has no glucose ; three times the amount of sodium pyruvates ; and more than four times the amount of sodium lactate . in table 2 there is shown that most concentrations of sodium lactate are at least two times the level of the resucitation culture medium of this invention . this embodiment of the resucitation culture medium of this invention has balanced and added ingredients to best culture and allow the embryos to revive after thawing . the invention includes the addition of fatty acids , lipioc acid in a concentrations of from 0 . 000004 to 0 . 0000012 g / l , with a preferred concentration of 0 . 000008 g / l , and linoleic acid in concentrations of from 0 . 000002 to 0 . 000008 g / l , with a preferred concentration of 0 . 00005 g / l . these fatty acids may be supplemented with similar performance fatty acids . since many changes and variations of the disclosed embodiment of the invention may be made without departing from the inventive concept , it is not intended to limit the invention except as required by the appended claims .
a medium solution which will increase the growth , survival and ultimately the live birth rate of oocytes and embryos which have been or will be subjected to cryopreservation . the solution contains varied amounts of glucose , pyruvates , amino acids , vitamins k5 and c , antioxidants , fatty acids to supply the specimens with the chemical ingredients and uptake requirements required to recover and prosper during and after the cryopreservation process . the solution supplies nutrients to the specimens that will replenish depletion and damage to the specimens and their mitochondria , spindles and structural features , such as cell walls . one formulation addresses the additional requirements of frozen specimens as opposed to the current media solutions and methods which treat the un - frozen specimens the same as the frozen specimens when recovering them from cryopreservation .
