spermatocytes การใช้

• Primary spermatocytes are diploid ( 2N ) cells containing 46 chromosomes.
• Spermatocytes develop from the transformation of choanocytes and oocytes arise from archeocytes.
• Secondary spermatocytes are haploid ( N ) cells that contain 23 chromosomes.
• Each secondary spermatocyte will form two spermatids after Meiosis II.
• After Meiosis I, two secondary spermatocytes are formed.
• MSP is exclusively synthesized in spermatocytes of the nematodes.
• Alternatively they go on to differentiate into spermatocytes, spermatids and finally spermatozoa.
• Here the spermatocytes pass through the basal membrane via the sertoli cell barrier.
• The tail or " flagellum " executes the lashing movements that propel the spermatocyte.
• There are two types of spermatocytes, primary and secondary spermatocytes ( Figure 1 ).
• There are two types of spermatocytes, primary and secondary spermatocytes ( Figure 1 ).
• Primary and secondary spermatocytes are formed through the process of spermatocytogenesis ( Figure 3 ).
• Asynaptic regions are associated with BRCA1, kinase ATR and ?H2AX presence in pachytene spermatocytes.
• This gene is expressed primarily in spermatocytes.
• The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.
• It is observed on spermatogonia and primary spermatocytes, and in some prostate and breast cancers.
• The protein localizes to the axial elements of chromosomes during meiosis in both oocytes and spermatocytes.
• It is suggested that a passive mechanism involving asynaptic region clustering in spermatocytes is a possible cause.
• NLRP14 is found exclusively in the testes where it is expressed within spermatogonia, spermatocytes and spermatids.
• Spermatocytogenesis is the male form of secondary spermatocytes, which will later divide once more into haploid spermatids.
