To investigate the technique of sorting high-purity precartilaginous stem cells from rat's perichondrium, neonatal rat's perichondrium cells suspensions were incubated with monoclone antibody of anti-fibroblast growth factor receptor-3 (anti-FGFR-3), and the labeled cells were separated from the suspension in the magnetic field by immuno-beads coated with the second antibody. Purity of the sorted neural stem cells was found to be 93.0%-99.0%, with living cells amounting to 80% -85 %. The magnetic cell sorting system could effectively separate precartilaginous stem cells from perichondrium cell suspensions.

Objective To research the antibacterial effect in vitro of different extract of Wikstroemia indica.Methods Double dilution method was used to determine the MIC of 11 species bacterium.Results The acetic ether extract had much obvious effect than n-butanol extract,both of them had high effect on staph.,but the aqueous extract had little antibacterial effect.Conclusion The acetic ether extract has obvious antibacterial effect,also has broad-spectrum antibacterial activity.

The PIWI family members are defined as conserved PAZ and PIWI domains and play important roles in stem-cell self-renewal,spermatogenesis,RNA interference and translational regulation.Recent researches have showen that some PIWI are specifically expressed in tumors and associated with tumor development and growth.PIWI is likely to be a new significante index for tumor diagnose and prognosis,the feasibility of PIWI acting in tumor gene theropy could be in vestigated by studying the mechanism of PIWI expression and regulation.

95%). Conclusion Immunomagnetic separation can effectively isolate and purify PSCs.
