Asi, ciertos tejidos orales postnatales podrian emplearse como fuente de celulas epiteliales, entre los que incluye celulas madre progenitoras del epitelio oral (OESCs); los restos epiteliales de Malassez (ERM) presentes en el ligamento periodontal (PDL) en la vaina epitelial radicular de Hertwig cerca de los extremos de una raiz en formacion; en el epitelio reducido del esmalte (REE) que cubre el esmalte durante la erupcion dental; el epitelio de union (JE) a nivel del cuello dentario; la lamina dental activa (DL) que se encuentra en el area retromolar a los 5 o 6 anos; los restos de la lamina dental del cordon
gubernacular (GC), presentes por encima de los dientes en erupcion (9).
With gentle traction on the testis, the most distal
gubernacular attachment was divided with electric hook cautery, and gubernaculum was used as a handle for mobilizing the testis.
Once this process is complete, the inguinal canal is dilated by the
gubernacular bulb and the testis pushed through the canal by changes in intra-abdominal pressure.
Phthalate ester-induced
gubernacular lesions are associated with reduced insl3 gene expression in the fetal rat testis.
Testicular torsion can occur at any age, including the prenatal and perinatal periods, In neonates, the testicle frequently has not yet descended into the scrotum, or has not had its
gubernacular attachment secure to the scrotal wall.
Other congenital factors associated with torsion include hypermobile testes, horizontal testicular lie, hyperactive cremasteric reflex and defective
gubernacular attachment.
The
gubernacular veins and external spermatic perforators were isolated and divided.
Frey also noted that defective ipsilateral
gubernacular development might predispose to crossed testicular ectopia.
The follicle maintains fibrous continuity with the lamina propria of oral mucosa by "
gubernacular cords", whose original positions are visible in young skulls as "
gubernacular canals".
(3,4) In an effort to minimize complications while maintaining comparable treatment success rates, we developed a novel subinguinal hydrocelectomy with
gubernacular sparing.
The role of insulin 3, testosterone, Mullerian inhibiting substance and relaxin in rat
gubernacular growth.
