When complete medium containing collagen was supplemented with nerve growth factor (NGF) DRG outgrowth was observed after 18 h. In the absence of NGF and in the presence of collagen, the DRG outgrowth took place after 72 h. In wells not supplemented with collagen gel in substratum, no DRG outgrowth was observed. Partially, DRG differentiation was observed in the presence of NGF. In the absence of NGF and collagen, there was no DRG outgrowth detected. It seems that, in some circumstances, cells degenerated by DRG may be an indication of an apoptosis phenomenon. Therefore, we suggested that collagen as a substratum is more effective than NGF SP - 101 EP - 105 AU - Firouzi, Massoumeh AU - Sabouni, Farzaneh AU - Ziaee, Abed-Ali AU - Taghikhani, Mohammad AD - KW - Collagen KW - Adherent substratum KW - Dorsal root ganglia KW - Culture KW - Neurite UR - http://ibj.pasteur.ac.ir/article-1-519-en.html ER -
