Homogenization-resistant spermatids in testicular tissue stored under suboptimal conditions-Effect of time and temperature

, 2018
Reproductive assessments on wild animals are often hampered due to practical problems during sample collection. For example, the time between death and tissue collection as well as sample storage conditions will affect the quality of the tissue.

Effects of FA concentration and exposure time on the membrane integrity of round spermatids.

, 2016
(A) PI nuclear staining was used to monitor membrane integrity over time when 8 or 16 μM AA was applied to round spermatids. (B) PI nuclear staining was used to monitor membrane integrity following induction with 16 μM AA, DHA, OA and PA for 15 min ...

Mutant spermatids show defective manchette structure, and abnormal head morphologies, suggesting defects in IMT.

, 2013
(A and B) TEM of elongating spermatids, highlighting the manchette with brackets. The manchette forms in Azi1Gt/Gt spermatids, although it often appears kinked (Figure S7A), or is misnucleated away from the spermatid head (B, black arrows, also see ...

Sperm characteristics as additional evidence of close relationship between Lebiasina and Piabucina (Characiformes: Lebiasinidae: Lebiasininae)

Neotropical Ichthyology
Spermiogenesis and spermatozoa of representatives of the genera Lebiasina and Piabucinaare described. Spermiogenesis is quite similar among all analyzed species of these genera and is identified as Type II.

FACS selection of valuable mutant mouse round spermatids and strain rescue via round spermatid injection

, 2015
Round spermatid injection (ROSI) into mammalian oocytes can result in the development of viable embryos and offspring. One current limitation to this technique is the identification of suitable round spermatids.

TMF^-/- spermatids lack an acroplaxome.

, 2016
Testicular sections from wt (A-D) and TMF-/- mice (E-F) were subjected to EM analyses. (A) Stage 2/early 3 wt spermatid. (B) Boxed area in A under higher magnification. The acroplaxome is marked by arrows. (C) Stage 4 wt spermatid.

Application of genome tagging technology in elucidating the function of sperm-specific protein 411 (Ssp411)

Asian Journal of Andrology
The genome tagging project (GTP) plays a pivotal role in addressing a critical gap in the understanding of protein functions. Within this framework, we successfully generated a human influenza hemagglutinin-tagged sperm-specific protein 411 (HA-tagged ...

Manchette structure in wild-type and Katnb1^Taily/Taily spermatids.

, 2012
A. α-Tubulin staining (green) of manchette microtubules in isolated spermatids from WT mice. Elongating spermatids are shown in progressive steps of manchette development from left to right.
