Differentiation The distinguishing of one thing or disease from another. The mathematical process of obtaining the derivative of a function.
Differentiation can involve changes in numerous aspects of cell physiology; size, shape, polarity, metabolic activity, responsiveness to signals, and gene expression profiles can all change during differentiation.
Differentiation In time, the cells of the embryo differentiate to form the specialized structures and functions that they will have in the adult. They form neurons, blood cells, skin cells, muscle cells, etc., etc.
Differentiation The series of biochemical and structural changes by which an unspecialized cell becomes a specialized cell with a specific function.
differentiation - process whereby cells acquire their mature morphological and biochemical characteristics. Differentiation is often considered a 'final step' of development in which cells take on their mature function.
differentiation Divergence in structure and function of cells as they become specialized during a multicellular organism's development; depends on the control of gene expression (cell differentiation).
Lack Differentiation Normally, cells become differentiated and become capable of specific functions. For example, muscle cells are specialized for contraction, nerve cells (neurons) are specialized for conducting signals, etc.
zone of differentiation Area in plant roots where recently produced cells develop into different cell types. zone of elongation Area in plant roots where recently produced cells grow and elongate prior to differentiation.
Differentiation and Genetic Cascades Development of a complex multicellular organism is more than just growth - we certainly do not look like gigantic fertilized eggs.
differentiation The chemical and physical changes associated with the developmental process of an organism or cell.
The differentiation of angïoblasts from the mesoderm occurs not only in the area vasculosa but within the embryo and probably most of the larger bloodvessels are developed in situ in this manner.

[edit] Cell differentiation in the epidermis The plant epidermis consists of three main cell types: pavement cells, guard cells and their subsidiary cells that surround the stomata and trichomes, otherwise known as leaf hairs.

Thrinaxodon has a reduced number of incisors, a precursor to tooth differentiation. Cynognathus (a doglike carnivore) shows a further increase in size of the dentary bone. The other three bones are located inside the back portion of the jaw.
The stimulated B cell undergoes repeated cell divisions, enlargement and differentiation to form a clone of antibody secreting plasma cells. Hence.
Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation.
Originating in embryology, modern developmental biology studies the genetic control of cell growth, differentiation, and "morphogenesis," which is the process that progressively gives rise to tissues, organs, and anatomy.
Cellular differentiation begins to form organs during the third week. After one month the embryo is 5 mm long and composed mostly of paired somite segments. During the second month most of the major organ systems form, limb buds develop.
Segre's research focuses on the dynamic process by which the epidermis maintains a proper balance between proliferation and differentiation.

A protein which is found in the bacterial genus Streptomyces that helps start the production of streptomycin and the process of morphological differentiation.
High FST implies a considerable degree of differentiation among populations. FIS (inbreeding coefficient) is the proportion of the variance in the subpopulation contained in an individual. High FIS implies a high degree of inbreeding.

spermiogenesis The process of differentiation by which haploid spermatids are transformed into mature spermatozoa.
Cells of multi-cellular organisms also receive signals from other cells, including signals for cell division and differentiation. The majority of cells in our bodies must constantly receive signals that keep them alive and functioning.
PROTO-ONCOGENE - A cellular oncogene-like sequence which is thought to play a role in controlling normal cellular growth and differentiation.
