Acid phosphatase activity in the chick ovary during embryonic development. 1984

M E Samar, and R E Avila, and S P de Fabro

Acid phosphatase activity was studied in the left and right ovaries of the chick during embryonic development. The cytochemical study indicated that local enzymatic activity is localized mainly in germ and somatic cells. From the results obtained in the study on the specific activity of this acid hydrolase, it can be inferred that the higher concentration of this enzyme in the right ovary would be determined by a decrease of total proteins in the total homogenate and in the cellular fractions of this organ. Besides, a decrease in the enzymatic activity of this ovary is not observed, but it occurs in the left ovary. This finding would indicate a lack of enzymatic segregation that could be related to the phenomenon of ovarian atrophy. Finally, the electrophoretic study indicated that it would apparently exist only one molecular form of the enzyme. Our results support the hypothesis that acid phosphatase would be involved in the atrophic processes of the right ovary during embryonary differentiation.

UI MeSH Term Description Entries
D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick
D005260 Female Females
D006128 Growth Gradual increase in the number, the size, and the complexity of cells of an individual. Growth generally results in increase in ORGAN WEIGHT; BODY WEIGHT; and BODY HEIGHT.
D000135 Acid Phosphatase An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.2. Acid beta-Glycerophosphatase,Acid beta Glycerophosphatase
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
