Apoptosis
... during an organism's life cycle. For example, the
differentiation of human fingers in the developing embryo ... which B and T cells are driven to proliferation,
differentiation or apoptosis comprises a complex interplay ... of the nervous system, but cell lineage and
differentiation inevitably led to the study of cell fate: "One ...
Morphogenesis
... with the control of cell growth and cellular
differentiation . Morphogenesis is concerned with the shapes of ... various specialized cell types. Cell growth and
differentiation can take place in cell culture or inside of tumor ... can diffuse and carry signals that control cell
differentiation decisions in a concentration-dependent fashion. ...

T cell

Thymocytes are immature T cells. The
differentiation called thymic education occurs in a few stages ... midstage of T cell differentiation. At the end of
differentiation they express TCRs, CD3, CD4 and CD8 molecules. ... It is important to note that not only is the
differentiation of T cells controlled by thymic ...
Alga
... Filamentous - a string of non-motile cells connected together, sometimes branching
Parenchymatous - cells forming a thallus with partial
differentiation of tissues
In three lines even higher levels of organization have been reached, leading to organisms with full tissue differentiation. These are ...
Anabolism
... organism level is as anabolic or catabolic .
Anabolic processes tend toward "building up" organs and tissues. These processes produce growth and
differentiation of cells and increase in body size, a process that involves synthesis of complex molecules. Examples of anabolic processes include growth and ...

Lichen
... elongated outgrowths from the thallus that break off for dispersal. Fruticose lichens in particular can easily fragment. Due to the relative lack of
differentiation in the thallus, the line between diaspore formation and vegetative reproduction is often blurred. Many lichens break up into fragments when they dry, ...

Prions have also been speculatively linked to memory [2] and cellular

Stem cell
... hemopoietic stem cells . Until recently it was thought that each of these cells could produce just one particular type of cell—this is called
differentiation (see Morphogenesis ). However in the past few years, evidence has been gathered of stem cells that can transform into several different forms. ...
