We have previously shown that Chinese hamster ovary (CHO) cells capable of growing in medium free of exogenous proteins die by apoptosis during all stages of a batch culture (Zanghi et al., 1999). On the basis of the hypothesis that extracellular death factors might be important in apoptosis under these conditions, we examined the effect of the growth factor inhibitor and antitumor agent surami...
Lymphoid tissues cultured either as tissue blocks or as cell suspensions are used to study the behaviour of immune cells within their habitat. The preservation of tissue structures in tissue blocks, which is considered to be a major advantage, has been poorly defined. We characterised the morphological evolution of tissue cultures from human palatine tonsils and compared their lymphocyte subset...
introduction: both initiation and maintenance of spermatogenesis are hormonally regulated by fsh and testosterone. in this study, the effects of fsh and testosterone on the in vitro maturation of fresh and frozen- thawed round spermatids were determind. material and methods: cell suspension was isolated from testis of nmri male mice (8-10 weaks old) and divided into two groups .the first part w...
