while the rp.0.10 stroma cells induced the pro-b clones to differentiate into igm+ b cells but not t3+ t cells when cultured in the presence of lps and ril-3 , the b-cell progenitor clones gave rise to significantly higher numbers of igm+ b cells ( up to 63 % ) and to many more b cells expressing higher levels of surface igm when cocultured with ril-7 , lps , and rp.0.10 stroma cells .
