Programmed Cell Death in Preovulatory Ovine Follicles

Programmed cell death in preovulatory ovine follicles.

Apoptosis is a mode of physiological cell death that occurs during tissue regression and remodeling; it is characterized by macromolecular protein synthesis, oligonucleosomal fragmentation, nuclear condensation, cytoplasmic shrinkage, and dissociation of cell-to-cell junctional complexes. Direct in situ fluorescence detection of digoxigenin end-labeled genomic DNA was used as a marker of nuclea...

Different cell death types determination in juvenile mice ovarian follicles

Follicular atresia is a phenomenon that leads to evacuation of the ovary from the oocytes and the occurrence of menopause. The contribution of various types of cell death in atresia at different follicular developmental stages requires extensive investigation. In this study, we evaluated 3 types of programmed </...

Programmed cell death in Dictyostelium.

Programmed cell death (PCD) of Dictyostelium discoideum cells was triggered precisely and studied quantitatively in an in vitro system involving differentiation without morphogenesis. In temporal succession after the triggering of differentiation, PCD included first an irreversible step leading to the inability to regrow at 8 hours. At 12 hours, massive vacuolisation was best evidenced by confo...

Apoptosis: programmed cell death.

C urrently there is much interest and excitement in the understanding of how cells undergo the process of apoptosis or programmed cell death. Understanding how, why, and when cells are instructed to die may provide insight into the aging process, autoimmune syndromes, degenerative diseases, and malignant transformation. This review focuses on the development of apoptosis and describes the proce...
