These spores are inactive cells protected by resistant cell walls, and become new amoebae once food is available. In Acytostelium, the sorocarp is supported by a stalk composed of cellulose, but in other dictyostelids the stalk is composed of cells, sometimes taking up the majority of the original amoebae. With a few exceptions, these cells die ...
Clay had signed a one-year deal with ABC that kept him from working with other networks. [30] In July 1993, Clay released No Apologies , the first stand-up concert pay-per-view special. [ 33 ] It was purchased by over 250,000 homes and was the highest-grossing non-sports pay-per-view event of the year. [ 21 ]

The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus , which separate the chromosomes during cell division .
Sertoli cells function to nourish the developing sperm cells. They secrete androgen-binding protein, a binding protein which increases the concentration of testosterone. There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis.
Andrew Dice Clay is dealing with Bell’s palsy, but insists it's not a big deal and he's as "gorgeous" as ever. On Friday it was reported the comedian and actor, 63, had developed the condition ...
The walls of seminiferous tubules are lined with primitive germ layer cells and by Sertoli cells. [1] The barrier is formed by tight junctions, adherens junctions and gap junctions between the Sertoli cells, which are sustentacular cells (supporting cells) of the seminiferous tubules, and divides the seminiferous tubule into a basal compartment (outer side of the tubule, in contact with blood ...
The centrosome is copied only once per cell cycle, so that each daughter cell inherits one centrosome, containing two structures called centrioles. The centrosome replicates during the S phase of the cell cycle. During the prophase in the process of cell division called mitosis, the centrosomes migrate to opposite poles of the cell. The mitotic ...
