are cells characterized by one basophilic nucleolus; dispersed chromatin, extremely narrow and weakly basophilic cytoplasm (Fig.
Maturity Main Main macroscopic features of each phases histological phase features of each phase Immature Oogonia
, PG Ovaries small, translucent, gray, white, milky, or pink, occupy less than 1/5 of the body cavity.
(A) Nest of oogonia
is surrounded and among pre-follicle cells, forming germline cysts.
While the sagittal section of a normal ovary showed the different stages of oogenesis from oogonia
until mature oocytes (Fig.
The primordial germ cells give rise to nests of primary and secondary oogonia
through a series of mitotic divisions.
scriptum, the oogenesis process was divided into five stages, considering the oogonia
as STAGE I.
The morphologic features of their hyphal and other structures developed in these media, including oogonia
, were microscopically investigated.
RSPO1/beta-catenin signaling pathway regulates oogonia
differentiation and entry into meiosis in the mouse fetal ovary.
The first are oogonia
(female) and antheridia (male), developing mostly at branchlet nodes.
Previous studies reported that the lacunae are related to elimination of dead oogonia
[65-67], whereas the fatladen cells are associated with a steroid production .
Based on morphological characterization, the foot rot pathogen exhibited globose oogonia
with paragynous antheridia, chlamydospore, torulose hyphae and lemon shaped sporangia with long pedicel.
Identification was based on colony morphology, mycelial characteristics, cardinal growth temperatures, morphology and dimensions of sporangia, oogonia
and antheridia as follows; Colony morphology and growth temperature: A 5-mm-diameter mycelial plug of each isolate was transferred to ACMA and incubated at 5, 24 and 35 [degrees]C for 7 days in the dark.
