WebMay 30, 2001 · Abstract. Autonomous cell specification is a form of specification in which the developing cell is able to differentiate (express proteins typical of the mature cell) … In terms of developmental commitment, a cell can either be specified or it can be determined. Specification is the first stage in differentiation. A cell that is specified can have its commitment reversed while the determined state is irreversible. There are two main types of specification: autonomous and conditional. A cell specified autonomously will develop into a specific fate based upon cytoplasmic determinants with no regard to the environment the cell is in.

There are three general ways a cell can become specified for a particular fate; they are autonomous specification, conditional specification and syncytial specification. This type of specification results from cell-intrinsic properties; it gives rise to mosaic development. The cell-intrinsic properties arise from a cleavage of a cell with asymmetrically expressed maternal cytoplasmic determinants (proteins, small regulatory RNAs and mRNA). Thus, the fate of the ce… WebSep 23, 2005 · Abstract Autonomous cell specification is a form of specification in which the developing cell is able to differentiate (express proteins typical of the mature cell) …

WebCharacteristic of most invertebrates. 2. Specification by differential acquisition of certain cytoplasmic molecules present in the egg. 3. Invariant cleavages produce the same lineages in each embryo of the species. Blasto- mere fates are generally invariant. 4. Cell type specification precedes any large-scale embryonic cell migration. 5.

Webcell specialization depends on a pair of proteins that act as super regulators of proteins that were already known—one super-regulating protein encouraging a cell to differentiate and the other trying to hold back the process.
