Liver Cell Transplantations Stabilized by Mesenchymal Stem Cells

Mesenchymal Stem Cells were shown to release factors to aid in hepatocyte regeneration.

Researchers at King’s County Hospital, London, have found that co-culturing hepatocytes [liver cells] with human mesenchymal stem cells [The same type found in Dental Stem Cells] improves hepatocyte survival and function.  They found that in the presence of hepatocytes, the MSCs produced pro-survival factors, which supported the growth of the hepatocyte culture.

NY Times Reports on Fabricating Livers from Stem Cells

'Liver buds' in culture plate

Researchers at Yokohama City University in Japan created tiny human livers utilizing human stem cells.   The rudimentary livers [which were transplanted into mice] grew, made human liver proteins, and metabolized drugs as human livers do.  And while the liver buds, as they are called, did not turn into complete livers, the study represents an important step in developing methodologies for growing large, complex organs.

Researchers all around the world are working towards utilizing stem cells to grow replacement organs. While once thought to be a futuristic concept, it is now very real. Doctors and researchers have successfully transplanted lab grown bladders, blood vessels, tear ducts, arteries and windpipes. Now, research teams around the world are growing urethras, bile ducts, larynxes, bones, livers, kidneys, and even hearts.

“Ninety percent of the patients on the transplant list are actually waiting for a kidney. Patients are dying every day because we don’t have enough of those organs to go around,” explained Anthony Atala, a leading stem cell researcher from Wake Forest during a TED talk.  Given this acute need for organs, researchers around the world are racing to develop techniques to grow organs and tissue with stem cells.

Researchers Utilize Stem Cells to Grow Livers and Eye Balls

Stem cell biologist Takanori Takebe of Yokohama City University in Japan successfully grew a small rudimentary liver while at the RIKEN Center for Developmental Biology in Kobe, researcher Yoshiki Sasai and his colleagues directed “retinal precursor cells” to develop into an the optic cup of the eye.  Takebe said “a more developed version of the liver could eventually be used for long-term organ replacement, as well as serving as a short-term graft for patients whose damaged native livers are expected to recover.” Both the liver research and the optical tissue regeneration are examples of how advances in directing cells to differentiate will accelerate the application of stem cell treatments.
