The nuclei are often in a linear string of beads" arrangement separated from the tubule lumen by an adluminal
arrangement of uniform Sertoli cell nuclei.
Estas uniones se abren transitoriamente para permitir el paso hacia adluminal
de las celulas germinales en su transito hacia el lumen.
While advancing through the long meiotic prophase I, spermatocytes undergo several changes such as chromosome condensation, genetic recombination and migration from the basal to the adluminal
compartment of the seminiferous tubule through the BTB/SC barrier .
The tight junctions between Sertoli cells form a blood-testis barrier (BTB), which physically divides the seminiferous epithelium into basal and adluminal
Spermatocytes round and elongated spermatids and spermatozoids were observed in the adluminal
At day 21 simple coiled tubular glands were observed throughout the endometrial stroma to the adluminal
border of the myometrium.
These cells showed little variation in size and shape and formed a column of cells towards the adluminal
surface of the horns.
Transferrin gene codes the formation of the iron transport glycoprotein, transferrin which is important in the delivery of iron to germinal cells within the adluminal
compartment of the seminiferous tubules (55-56).
Dentre a regulacao intrinseca, destacam-se as celulas de Sertoli, portadoras de dobras complexas em seu plasmalema e juncoes de oclusao em suas membranas laterais, subdividindo o epitelio seminifero em dois compartimentos: basal, contendo espermatogonias e espermatocitos primarios e adluminal
, contendo espermatocitos primarios tardios, espermatocitos secundarios, espermatides e espermatozoides.
Two meiotic divisions and the spermiogenesis normally occur in the adluminal
microenvironment (Jiang et al.
From 10 weeks of age, cPdcl2 mRNA expression was detected within the adluminal
In summer, the luminal and adluminal
plasma membrane of the endothelial cells showed numerous folds and their cytoplasm contained mostly electron lucid transendothelial vesicles.
