These tissues are composed of a hierarchy of cells: at one end of the hierarchy are stem cells which are less differentiated and can divide without limit; at the other end are mature cells which are highly differentiated and have no capac不确定 发表于 2025-3-26 01:40:10
Thomas Kristntrol the function of this gland. Research on control of luteal function has encompassed a broad spectrum of mammalian taxa and has evolved from early studies to identify the source and nature of controlling factors to present day attempts to resolve their action at the level of the luteal cell.

The classical viewpoint (Fig. 1) regards CPK as a near equilibrium enzyme buffering cytosolic changes in nucleotide concentration (1,2), with creatine phosphate representing a reservoir of high energy phosphate equivalents (3) and with regulation of ene指数 发表于 2025-3-26 18:49:39
