1. In male animals, the reproductive cell whose nucleus is capable of fusing with the nucleus of an egg cell to form a new organism; a spermatozoon. A sperm has half as many chromosomes as the other cells of the body and moves to unite with the egg. 2. In plants, algae, and certai...
2.(Anatomy) a structure, such as a lymph node, that resembles a gland in form 3.(Botany) a cell or organ in plants that synthesizes and secretes a particular substance [C17: from Latinglānsacorn] ˈglandˌlikeadj gland (ɡlænd) ...
In addition, we resolved another in-cell structure of DMT from the deformed sperm axoneme and structural comparison with the intact sperm axoneme showed a superior stability of A-tubule than B-tubule in DMT. These findings not only reveal the specialized DMT structure of mammalian sperm, but...
R2/1 Quantifoil grids with hole sizes of ~2 μm were chosen to increase cell coverage. The TEM grids were blotted from the reverse side and immediately plunged into a liquid ethane/propane mixture at liquid nitrogen temperature using a custom-built vitrification device (MPI, Martinsried, ...

The mature sperm cell (spermatozoon) is highly polarized with a nuclear head structure at one end and a flagellum at the other end to propel itself through the female reproductive tract. In the mammalian testes, the seminiferous tubules support the development of spermatogonia (undifferentiated male...

Using 10× Chromium single-cell sequencing technology, we assessed the transcriptome from >65,000 single spermatozoa across six sperm donors (scSperm-RNA-seq), including two who fathered multiple children with ASD and four fathers of neurotypical children. Using RNA-seq methods for differential ...
2. Biology The structure in the cytoplasm of a living cell that contains the cell's DNA and controls its metabolism, growth, and reproduction. A nucleus surrounded by a membrane is found in almost all the cells of eukaryotes and thus sets them apart from the cells of prokaryotes, such as...
STYXL1 is a germ cell-specific pseudophosphatase in testis Protein phosphatases are key regulators of many cellular processes and diseases27. To investigate the role of protein phosphatases in testis, we first analyzed their expression patterns. Among 233 phosphatases2823 were testis-enriched29,30(Fig...
