mitochondria from stem cells to recipient cells is regulated by the protein Miro1 and is part of a well - directed process,» remarked Anurag Agrawal, Professor at the CSIR - Institute of Genomics and Integrative Biology in Delhi, India, and one of the lead authors of the study.
In the study, the protein Miro1 was shown to regulate the transfer of
mitochondria from mesenchymal stem cells to epithelial cells.
They then proceed to disintegrate the sperm's outer membrane and separate
the mitochondria from the tail section, which is subsequently cut into smaller pieces that are then «devoured» by conventional selective autophagy.
This gives the baby three genetic parents: DNA in the nucleus from the mother and father, and that of
the mitochondria from the donor.
Scientists can replace the mitochondria of the mother's egg cell with
mitochondria from a healthy donor.
They found that by attaching to a mitochondrial protein called TOM20, alpha - synuclein prevented
the mitochondria from functioning optimally, which resulted in the production of less energy and more damaging cellular waste.
And once entire
mitochondria from one plant get into the cells of another, they mix their DNA with that of the existing mitochondria.
