27 g . the number of cells recovered per g of amnion was about 10 - 15 × 10 6 for dissociation with pxxiii method of obtaining selected amp cells — amnion epithelial cells were plated immediately upon isolation from the amnion . after ˜ 2 - 3 days in culture non - adherent cells were removed and the adherent cells were kept . this attachment to a plastic tissue culture vessel is the selection method used to obtain the desired population of amp cells . adherent and non - adherent amp cells appear to have a similar cell surface marker expression profile but the adherent cells have greater viability and are the desired population of cells . adherent amp cells were cultured in basal medium supplemented with human serum albumin until they reached 120 , 000 - 150 , 000 cells / cm 2 . at this point , the cultures were confluent . suitable cell cultures will reach this number of cells between ˜ 5 - 14 days . attaining this criterion is an indicator of the proliferative potential of the amp cells and cells that do not achieve this criterion are not selected for further analysis and use . once the amp cells reached 120 , 000 - 150 , 000 cells / cm 2 , they were collected and cryopreserved . this collection time point is called p0 . the amp cells of the invention can be used to generate accs , including pooled accs . the amp cells were isolated as described above and about 1 × 10 6 cells / ml were seeded into t75 flasks containing ˜ 10 ml culture medium as described above . the cells were cultured until confluent , the medium was changed and accs was collected ˜ 3 days post - confluence . optionally , the accs is collected again after 3 days , and optionally again after 3 days . skilled artisans will recognize that other embodiments for collecting accs from confluent cultures , such as using other tissue culture vessels , including but not limited to cell factories , flasks , hollow fibers , or suspension culture apparatus , etc . are also contemplated by the methods of the invention ( see detailed description above ). it is also contemplated by the instant invention that the accs be cryopreserved , lyophilized , irradiated or formulated for sustained - release , etc ., following collection . it is also contemplated that accs be collected at different time points ( see detailed description for details ). accs was obtained essentially as described above . in certain embodiments , accs was collected multiple times from an amp cell culture derived from one placenta and these multiple accs collections were pooled together . such pools are referred to as “ sp pools ” ( more than one accs collection / one placenta ). in another embodiment , amp cell cultures were derived from several placentas , i . e . from 5 or 10 placentas . the amp cells from each placenta were cultured and one accs collection from each culture was collected and then they were all pooled . these pools are termed “ mp1 pools ” ( one accs collection / placenta , multiple placentas ). in yet another embodiment , amp cell cultures were derived from several placentas , i . e . from 5 or 10 placentas . the amp cells from each placenta were cultured and more than one accs collection was performed from each amp cell culture and then pooled . these pools are termed “ mp2 pools ” ( more than one accs collection / placenta , multiple placentas ). inflammatory model — use of accs to prevent onset of periodontal disease in an animal model objective : the aim of this study was to evaluate the preventive role of accs in porphyromonas gingivalis ( p . gingivalis )- induced experimental periodontitis in rabbits methods : eight new - zealand white rabbits were distributed into 3 groups : 1 . untreated ( n = 2 ), 2 . control ( unconditioned accs culture media ) ( n = 3 ), and 3 . accs ( n = 3 ). at baseline , all rabbits received silk ligatures bilaterally tied around mandibular second premolars under general anesthesia . the assigned test materials , accs or control , in volumes of 10 μl were topically applied to the ligated sites with a blunt needled - hamilton syringe from the time of ligature ; control animals received ligature , but no treatment . topical p . gingivalis - containing slurry ( 1 ml ) was subsequently applied to induce the periodontal inflammation . the application of test materials and p . gingivalis continued for 6 weeks on an every - other - day schedule . at 6 weeks , following euthanasia , the mandibles were surgically harvested . morphometric , radiographic and histologic evaluations were performed . results : macroscopic evaluations including soft tissue assessments , crestal bone and infrabony measurements showed significant periodontal breakdown induced by p . gingivalis in control and no treatment groups at 6 weeks compared to historical ligature - alone groups ( p = 0 . 05 , p = 0 . 03 , respectively ). accs application significantly inhibited soft tissue inflammation and prevented both crestal bone loss and infrabony defect formation compared to untreated and control groups ( p = 0 . 01 , p = 0 . 05 , respectively ). histologic assessments and histomorphometric measurements supported the clinical findings ; accs treated animals demonstrated significantly less inflammation in soft tissue and less bone loss compared to the untreated and control groups ( p = 0 . 05 ). conclusions : topical accs application prevents periodontal inflammatory changes and bone loss induced by p . gingivalis as shown both at clinical and histopathological level . accs has potential as a therapeutic approach for the prevention of periodontal diseases inflammatory model — use of accs to stop progression of or reverse periodontal disease in an animal model objective : the aim of this study was to evaluate the therapeutic actions of accs in the treatment of periodontitis induced by p . gingivalis . methods : the study was conducted using a two - phase rabbit periodontitis protocol : 1 — disease induction ( 6 weeks ) and 2 — treatment ( 6 weeks ). periodontal disease was induced in 16 new - zealand white rabbits by every - other - day application of topical p . gingivalis to ligatured mandibular premolars . at the end of phase 1 , 4 randomly selected rabbits were sacrificed to serve as the baseline disease group . for phase 2 , the remaining 12 rabbits were distributed into 3 groups ( n = 4 ), 1 — untreated , 2 — control ( unconditioned accs culture media ) and 3 — accs treatment . at the end of phase 2 , morphometric , radiographic and histologic evaluations were performed on harvested mandibles . results : the baseline disease group exhibited experimental periodontitis evidenced by tissue inflammation and bone loss . at the end of phase 2 , the untreated group showed significant disease progression characterized by increased soft and hard tissue destruction ( p = 0 . 05 ). the tissue inflammation and bone loss was significantly reduced by topical accs compared to baseline disease and untreated groups ( p = 0 . 05 ; p = 0 . 002 , respectively ). the control treatment also arrested disease progression compared to untreated group ( p = 0 . 01 ), but there was no improvement in periodontal health compared to baseline disease ( p = 0 . 4 ). histopathological assessments revealed similar findings ; accs stopped the progression of inflammatory process ( p = 0 . 003 ) and reversed bone destruction induced by p . gingivalis ( p = 0 . 008 ). the accs - treated group had minimal osteoclastic activity limited to crestal area compared to untreated and control groups , which showed a profound osteoclastogenic activity at the bone crest as well as at interproximal sites . conclusions : topical application of accs stopped the progression of periodontal inflammation and resulted in tissue regeneration in rabbit periodontitis indicating its potential therapeutic efficacy . inflammatory model — evaluate the efficacy of topically applied accs to inhibit irritant 12 - o - tetradecanoylphorbol - 3 - acetate ( tpa ) skin inflammation in mice method : topical treatment was given twice daily to the following groups : 1 . tpa + topical control ; 2 . tpa + accs ; 3 . tpa + clobetasol 0 . 05 topical solution ( the strongest available topical corticosteroid ); 4 . accs alone ; 5 . no treatment ( the other untreated ear was measured ). the endpoints for the study were ear thickness and ear weight at the end of the experiment . the thicker the ear and the more it weighs correlates with the degree of inflammation . results : topically applied accs was effective at reducing the inflammation induced by tpa . the anti - inflammatory activity of topical accs reached the same level as clobetasol ( a class 1 potent topical corticosteroid ) by 3 days after beginning application . conclusion : accs has a strong anti - inflammatory effect when applied to skin . inflammatory model — evaluate the efficacy of intralesional injection of accs to inhibit irritant ( tpa ) skin inflammation in mice method : intralesional injection into the ear was given once daily to the following groups : 1 . tpa + intralesional control ; 2 . tpa + intralesional accs ; 3 . tpa + intralesional kenalog ( 10 mg / ml ) ( a potent intralesional corticosteroid ); 4 . accs intralesional injection alone ; 5 . saline sham injections to the normal untreated ear . the endpoints for the study were ear thickness and ear weight at the end of the experiment . the thicker the ear and the more it weighs correlates with the degree of inflammation . results : intralesional injection of accs was effective at reducing the inflammation induced by tpa at all time points beginning on day 2 of daily injections . intralesional kenalog ( 10 mg / ml ) injections induced a hematoma at the site of injection , which led to some inflammation and that is why there is not a substantial difference in ear thickness when comparing tpa + kenalog with tpa + control . conclusions : intralesional accs did reduce skin inflammation but the topically applied accs in example 1 above had a more potent effect . there was no difference in ear weight using either accs or intralesional kenalog compared with tpa + control . an art - accepted animal model for chronic granulating wound was used to study the effects of accs on chronic wound healing ( hayward pg , robson mc : animal models of wound contraction . in barbul a , et al : clinical and experimental approaches to dermal and epidermal repair : normal and chronic wounds . john wiley & amp ; sons , new york , 1990 .). results : accs was effective in not allowing proliferation of tissue bacterial bioburden . accs allowed accelerated healing of the granulating wound significantly faster than the non - treated infected control groups . accs compositions are tested in animal models of organ transplant to evaluate their ability to prevent , modulate , reduce , treated or ameliorate ischemic injury in the harvested organ . standard animal models of organ transplantation are found in the scientific literature as well as in “ handbook of animal models in transplantation research ”, edited by donald v . cramer , luis podesta and leonard makowka , published in 1993 by crc press ( incorporated herein by reference ). accs compositions are tested for their ability to prevent , modulate , reduce , treated or ameliorate ischemic tissue injuries . the experimental approach includes testing accs compositions in a hind limb ischemia model . this model utilizes a controlled tension tourniquet circumferentially around the proximal thigh of a mouse for 3 hours . reperfusion is initiated by release of tension on the tourniquet . immediately following reperfusion , accs compositions are injected into the left ventricle . perfusion - restoration of blood flow is monitored by laser doppler flow imaging . immunohistochemistry and quantitative pcr are used to assess accelerated tissue neovascularization and angiogenesis . preservation / storage — use of accs as a storage preservative for donated tissues and organs the successful outcome of the majority of corneal transplants depends on the presence of a viable corneal endothelium . since human corneal endothelial cells do not readily proliferate , preservation of the endothelium is a primary aim of methods of corneal storage . although some cryopreserved corneas have been transplanted successfully , the complexity of the standard cryopreservation technique and its potential for causing endothelial damage have limited its application . because of its anti - inflammatory properties , accs is tested for its ability to preserve corneas for transplant . the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof . any equivalent embodiments are intended to be within the scope of this invention . indeed , various modifications of the invention in addition to those shown and described herein will become apparent to those skilled in the art from the foregoing description . such modifications are also intended to fall within the scope of the appended claims . throughout the specification various publications have been referred to . it is intended that each publication be incorporated by reference in its entirety into this specification .
