I did a quick search and found this: http://physiologyonline.physiology.org/content/28/6/414 http://physiologyonline.physiology.org/content/28/6/414 > First, in vitro intercellular organelle transfer has been described in a highly diverse > assortment of cell types, including human and rodent, differentiated and multipotent, > malignant and benign, epithelial and mesenchymal, and neuronal. Thus it is safe to > conclude that the capability of one cell to donate or receive an organelle from another > cell is clearly widespread throughout mammalian cell types in culture. Stressed cells being rescued from apoptosis by organelle transfer through tunneling nanotubes (TNTs): http://www.nature.com/cdd/journal/v22/n7/full/cdd2014211a.html http://www.nature.com/cdd/journal/v22/n7/full/cdd2014211a.ht... > Further studies demonstrated that microtubule-containing TNTs were formed by stressed cells, > which had lost cytochrome c but did not enter into the execution phase of apoptosis > characterized by caspase-3 activation.
