The aim of the present study was to investigate the BIO effects on in vitro expansion of rat marrow-derived mesenchymal stem cells (MSCs) culture. Methods: In the present experimental study, bone marrow cells from 7 rats were plated in the presence of 0.05, 0.01, 0.1, 1 and 1.5 µM of BIO and expanded through three successive subcultures. During the cultivation period, the cultures were statistically compared in terms of some indices of cell growth including the diameter and number of colonies, population doubling number (PDN) and the number of viable cells. Passaged-3 cells from all groups were examined whether or not they could differentiate into bone and adipose cells. Results: According to our results, the largest colonies were formed in the cultures with 0.1 and 1 µm BIO with diameter of respectively 1262.27±43.96 and 1335.71 ± 19.16 micrometer (P %> http://ppj.phypha.ir/article-1-484-en.pdf %P 57-67 %& 57 %! %9 Experimental research article %L A-10-280-1 %+ Stem Cell Department, Royan Institute %G eng %@ 24765236 %[ 2009
