But there are in almost every living organism thousands of cells that die spontaneously by a process which is called with some ambiguity “physiological” or “spontaneous” cell death.rods366 发表于 2025-3-29 06:31:43

We have named this “background cell death” (Pexieder, 1971c, 1972d). A definition and extensive discussion of “background cell death” together with the descPON 发表于 2025-3-29 17:11:28
A Case Study: Teaching About Islamlue of these observations for mammalian and especially human embryos ? Initial comparisons of the occurrence of cell death foci by Glücksmann (1951) have shown that these can be found in different vertebrate species. The research report by Menkes, Deleanu and lilies (1965) has shown that at least in鸵鸟 发表于 2025-3-29 22:37:52

We therefore chose the chick embryo heart bulbus as a model for further research, because of its key importance in heart septation, its accessibility to observation an
