Lack of species-specificity in mammalian sperm chemotaxis
(Academic Press Inc Elsevier Science, 2003)
Human sperm chemotaxis: Both the oocyte and its surrounding cumulus cells secrete sperm chemoattractants
(Oxford University Press, 2005-03)
Background: Human sperm chemotaxis to pre-ovulatory follicular fluid is well established in vitro. However, it is not known whether the female's oocyte-cumulus complex secretes sperm chemoattractants subsequent to ovulation ...
Reactive oxygen species are involved in the signaling of equine sperm chemotaxis
(BioScientifica, 2020-04)
Sperm chemotaxis may facilitate the finding of the oocyte. Only capacitated spermatozoa can orient their movement by chemotaxis,which as well as capacitation, is regulated in part by the cAMP-PKA pathway. Reactive oxygen ...
Chemotaxis detection towards chlorophenols using video processing analysis
(Elsevier Science, 2017-11)
To our knowledge, this communication is the first report of chemotaxis towards chlorophenols by any bacteria. We used a recently published method based on the agarose in-plug assay combined with video processing analysis ...
Chemotaxis of Capacitated Rabbit Spermatozoa to Follicular Fluid Revealed by a Novel Directionality-Based Assay
(Society for the Study of Reproduction, 2002-11-01)
Precontact communication between gametes is established by chemotaxis. Sperm chemotaxis toward factor(s) in follicular fluid (FF) has been demonstrated in humans and mice. In humans, the chemotactic responsiveness is ...
Growth-promotion of strawberry plants inoculated with Azospirillum brasilense
(Springer, 2010-02)
Azospirillum brasilense (strains REC3, RLC1, PEC5) were root inoculated in strawberry plants of the cultivars 'Milsei', 'Selva' and 'Camarosa' to assess plant growth-promoting effects. The bacteria were able to promote ...
Improved bovine in vitro embryo production with sexed and unsexed sperm selected by chemotaxis
(Elsevier Science Inc, 2018-12)
Assisted reproductive techniques (ART) have been widely used in farm animals in the last decades. Sexed cryopreserved spermatozoa, ovum pick up, in vitro embryo production and transfer constitute the ART that have ...
CXCL12-induced chemotaxis is impaired in T cells from patients with ZAP-70-negative chronic lymphocytic leukemia
(Ferrata Storti Foundation, 2010-05)
Background T cells from patients with chronic lymphocytic leukemia may play an important role in contributing to the onset, sustenance, and exacerbation of the disease by providing survival and proliferative signals to the ...
Chemotactic selection of frozen-thawed stallion sperm improves sperm quality and heterologous binding to oocytes
(Elsevier Science, 2020-10)
The successful use of assisted reproduction techniques (ART) depends in part on the sperm physiological status. Several sperm selection procedures have been applied to improve quality of sperm population when using the ...
Equine spermatozoa at optimum physiological state are selected by chemotaxis toward progesterone
(Elsevier Science Inc, 2018-07)
The success of assisted reproduction techniques depends inpart on sperm quality, which influences not only fertilization butalso embryo development and implantation. In our laboratory, wedesigned the Sperm Selection Assay ...
