A specialized region or structure similar to epididymis in mammals that participates on sperm cell
nutrition and maturation processes is lacking on the rooster reproductive tract.
(2) Raman Spectroscopy and Holographic Microscopy for Sperm Cell
Ascorbic acid addition in Tris egg yolk extender also improved sperm cell
membrane integrity of sahiwal cattle bulls shown in Table I.
Group one patients were divided further into two subgroups: group 1a included 56 cases in which TESE (testicular sperm extraction) was used to obtain the sperm cells
as the male factor was severe.
Fifty sperm cells
from each sample were optically trapped for analysis.
The concentration of sperm cells
was adjusted to 5x [10.sup.6] sperm/ml using Brackett-Oliphant (BO) medium containing heparin and 3% BSA.
The aperture used in this study was a long narrow channel, 46 [micro]m long (so that the passage of sperm cells
took >0.5 s), 7 [micro]m wide (the same as the width of aperture for a previous homemade microdevice) (24), and 11 [micro]m high (where the Makler chamber is 10 [micro]m in height), as illustrated in Fig.
Sperm: a silent cell?: One of the discussions in sperm cell
biology is whether any protein synthesis takes place in the sperm cells
The researchers also attempted to create sperm cells
using XX (female) stem cells, but concluded that the genes on the Y chromosome are necessary for sperm development and maturation.
At this point the hyperactivity of the sperm cell
In Eremobates sp., within the germinal part the sperm cells
are groups of a few, probably four, mature sperm cells
each surrounded by thin extensions of somatic cells.
In addition, PEI-mediated transport of FAM-labeled 10 mer oligonucleotide into abalone sperm cells
resulted in almost 100% bright fluorescent nuclei.
