tem cell scientists scored what at first appeared an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in bone marrow, can give rise to fat, bone, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair. Unfortunately, the results of these trials have been underwhelming. One problem is that these stem cells don’t stick around in the body long enough to benefit patients.
But Harvard Stem Cell Institute (HSCI) scientists at Boston Children’s Hospital aren’t ready to give up. A research team led by Juan Melero-Martin
The mesenchymal stem cells found in the bone marrow can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair.
Unfortunately, the results of these trials have been underwhelming, the main problem being that these stem cells do not stick around in the body long enough to benefit the patient.
Researchers have now found that transplanting mesenchymal stem cells along with blood vessel-forming cells naturally found in circulation improves results.
In 2010, L V Prasad Eye Institute (LVPEI) moved away from culturing corneal stem cells in a petri-dish in the laboratory to directly culturing and expanding them on the patient’s eye.
This ingenuous technique was termed Simple Limbal Epithelial Transplantation (SLET) to contrast it from the radical tissue transplants and complex culture techniques that were the standard of care at that time.
SLET completely eliminates the need for laboratory based processing thereby making it possible to be executed by any well trained surgeon anywhere (…)
A pilot clinical trial was done on a small sample size including 125 patients, 65 adults and 60
Taxus Cardium Pharmaceuticals Group Inc announced that the Company’s Excellagen flowable dermal matrix in combination with Orbsen Therapeutics’ mesenchymal stromal stem cell therapy Cyndacel-M has been selected for clinical evaluation in a Phase 1b safety study for the potential treaent of chronic diabetic wounds to be funded by the European Union under EU Framework 7.
The project, known by the acronym “REDDSTAR” (Repair of Diabetic Damage by Stromal Cell Administration), is being coordinated by Professor Timothy O’Brien, Dean of Medicine and Director of Ireland’s Regenerative Medicine Institute at National University of Ireland Galway.
In the initial phase of the project, academic
Harvard scientists have merged stem cell and ‘organ-on-a-chip’ technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease.
The research appears to be a big step forward for personalized medicine, as it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.
The work, published in Nature Medicine, is the result of a collaborative effort bringing together scientists from the Harvard Stem Cell Institute, the Wyss Institute for Biologically Inspired Engineering, Boston Children’s Hospital, the Harvard School of Engineering and Applied Sciences, and Harvard Medical
