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 Sex Sorting.
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 or not?
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 becomes important.
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.
