From there, the signals travel to the nucleus of each cell. Tissues are communities of cells that have functions beyond what any single cell type could accomplish. Healthy tissues require the ...

This article was originally published with the title “ Transplanted Nuclei and Cell Differentiation ” in Scientific American Magazine Vol. 219 No. 6 (December 1968), p. 24 doi:10.1038 ...

The nucleus of a germline stem cell undergoes two divisions, firstly separating homologous chromosomes and secondly separating chromatids. Haploid gametes contain 23 single chromosomes.

The importance of TGF-β family proteins in muscle cell differentiation is well illustrated by the effects of myostatin/growth development factor (GDF)-8, a TGF-β family member that is first ...

The IAEA's NUCLEUS information resource portal provides access to over 100 scientific, technical and regulatory resources, including databases, applications, publications and training material. As it ...

Gurdon showed that the identity of specialized cells could be changed. Gurdon replaced the nucleus of a frog egg with the nucleus ... the cell that produced the organoid is able to renew the tissue by ...

The first step in the process of generating embryonic stem cells is to remove the nucleus from an unfertilized egg cell (A). Because the egg cell is only 100 micrometers, or one-tenth of a ...

It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells. They created an array of ...

When a cell is placed on top of these nanopillars, the nucleus wraps itself around the nanopillars, causing its membrane to curve. This induced curvature in turn causes tiny, self-sealing openings ...

Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found ...

They created an array of nanopillars that can breach the nucleus of a cell—the compartment that houses our DNA—without damaging the cell's outer membrane. "We've developed a tool that can ...
