Cell Biology

Learn what mitochondria are, how their membranes and cristae support ATP production, and how mtDNA, dynamics and other functions contribute to cell biology.

Microbodies are small, single-membrane organelles found in eukaryotic cells that compartmentalize specialized metabolic reactions. The term is most closely associated with peroxisomes and specialized peroxisomal forms such as glyoxysomes, glycosomes, and Woronin bodies. Depending on the organism and cell type, these organelles participate in fatty-acid metabolism, hydrogen peroxide handling, photorespiration, the glyoxylate pathway, compartmentalized glycolysis,

Learn what mesenchymal stromal cells (MSCs) are, their markers, sources, differentiation, immune functions, mechanisms, clinical uses and limitations.

The epithelium of transition is a form of stratified epithelium that comprises several layers of cells, where their shape cells changes in accordance with the function that the organ performs. The epithelium can have a varied appearance, as it appears to be circular or cubic in a relaxed state with the exception of the apical layer that appears flat when stretched. The epithelium is essentially restricted to the urinary system that’s why it’s sometimes referred to”urothelium” “urothelium”.

Learn what prokaryotic cells are, their structure, characteristics, DNA, ribosomes, cell wall, reproduction, examples, and differences from eukaryotic cells.

Learn epithelial tissue definition, characteristics, structure, classification, types, functions, locations, examples, glandular epithelium and histology.

Vesicles are membrane-bound compartments that transport, store and release cellular materials. Learn their structure, types, functions, formation and vesicular transport.

may contain materials that must be eliminated from the cell. These materials could be harmful to cells, such as end products of chemical reactions or waste products.

Learn about cilia and flagella, including their axoneme structure, 9+2 arrangement, basal bodies, movement, functions, types, examples and differences.

Golgi apparatus is a membrane-bound organelle that modifies, sorts and packages proteins and lipids. Learn its structure, functions, cis-trans faces and diagram.
