Specifically, cell differentiation in animals is highly dependent on biomolecular condensates of regulatory proteins and enhancer DNA sequences. Cellular differentiation is often controlled by cell signaling. Many of the signal molecules that convey information from cell to cell during the control of cellular differentiation are called growth ...
Cellular atrophy is a decrease in cell size. If enough cells in an organ undergo atrophy the entire organ will decrease in size. Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called "disuse atrophy").
a type I transmembrane protein present on activated T and B cells that may play a role in cell activation and/or differentiation; expressed in Hodgkin disease, some T-cell lymphomas, and anaplastic large cell lymphomas. CD31: PECAM-1, a cell adhesion molecule on platelets and endothelial cells CD32A**
The CD nomenclature was proposed and established in the 1st International Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA), held in Paris in 1982. [4] [5] This system was intended for the classification of the many monoclonal antibodies (mAbs) generated by different laboratories around the world against epitopes on the surface molecules of leukocytes (white blood cells).
These then trigger traveling embryonic differentiation waves of contraction or expansion over presumptive tissues that determine cell type and is followed by cell differentiation. The cell state splitter was first proposed to explain neural plate morphogenesis during gastrulation of the axolotl [ 18 ] and the model was later generalized to all ...
Biofilm is a cell aggregate that can be attached to biological or abiotic surfaces. Bacteria form biofilms to adapt to various environments such as changes in substrate availability. For example, the formation of biofilm increases a bacterial cell's resistance to antibiotics compared to cells which are not part of the aggregate. [9]
Directed differentiation is a bioengineering methodology at the interface of stem cell biology, developmental biology and tissue engineering. [1] It is essentially harnessing the potential of stem cells by constraining their differentiation in vitro toward a specific cell type or tissue of interest. [ 2 ]
Anaplasia (from Ancient Greek ἀνά (ana) 'backward' and πλάσις (plasis) 'formation') is a condition of cells with poor cellular differentiation, losing the morphological characteristics of mature cells and their orientation with respect to each other and to endothelial cells.
