WebAbstract. Many different types of cells arise from the totipotent egg during embryonic development. Two distinct concepts have been formulated to explain how this diversity of cell types is generated. The first is that the egg already contains regionalized components known as cytoplasmic determinants that influence cell fate as a consequence of ... WebJan 3, 2024 · The presence of these cytoplasmic determinants drives the cell that contains them in specific developmental directions based on changes in gene …
WebAn asymmetric cell division produces two daughter cells with different cellular fates. This is in contrast to symmetric cell divisions which give rise to daughter cells of equivalent fates. Notably, stem cells divide asymmetrically to give rise to two distinct daughter cells: one copy of the original stem cell as well as a second daughter programmed to differentiate into a … WebA multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.

WebA multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity). During development, cells use both intrinsic ... WebApr 11, 2024 · Cytoplasmic determinants are also found in some post-embryonic cells, where they produce cytoplasmic asymmetry (q.v.). In dividing cells, this leads to …
