Exosomes are extracellular vesicles (EVs) of endosomal origin that range in size between 30 and 150 nanometers. Exosomes are secreted by a wide range of cells, since virtually all living cells utilize exosome-mediated communication. Exosomes carry cell-specific cargos of proteins, lipids, and nucleic acids that are selectively taken up by recipient cells. [Read more…]

What is the difference between totipotent, pluripotent, and multipotent?
When learning about stem cells, a common question is, what is the difference between totipotent, pluripotent, and multipotent cells? The answer is simple.
The key differences between these cells are:
- When each appears during the process of human development.
- Their degree of “flexibility” to become other cell types. [Read more…]
Behind the Scenes at FUJIFILM Irvine Scientific (FISI) with Yutaka Yamaguchi (President)
FUJIFILM Irvine Scientific (FISI) is the world’s leading manufacturer of cell culture media, reagents, and medical devices that are used across the cell therapy, regenerative medicine, assisted reproductive technology, and industrial cell culture markets.
