Small Endoplasmic Reticulum (Vesicle), a Substance Secreted by Cells

Among substances secreted from cells, small vesicles of nano size (about 30 ~ 150 nm) play an important role in signal transmission (communication) between cells. Because exosomes are bio-derived materials, they have less side effects and higher safety, and contain genetic factors such as DNA and RNA as well as bio-derived proteins. Exosomes derived from stem cells help cells grow, migrate, regenerate, and change the microenvironment around cells.
