Those hospitals and medical institutions advertising treatment of incurable diseases with stems cells are now under scanner of the Union Ministry of Health and Family Welfare. The ministry has already processed complaints against at least 23 website advertisements. The National Apex Committee for Stem Cell Research and Therapy (NACSCRT), under the Indian Council of Medical Research, has looped in Advertising Standards Council of India (ASCI) to monitor advertisements that claim to fully cure patients with stem cell based therapies. Several clinics and organisations advertise stem cell therapies whose safety and efficacy are not proven, to attract vulnerable patients. As per the National Guidelines for Stem Cell Research 2013, stem cell therapy has not been proven effective other than in Hematopoietic Stem Cell Transplantation (HSCT) for haematological disorders (disorders which primarily affect the blood). NAC-SCRT has observed that several clinicians, companies, hospitals advertise stem cell based therapies other than haematopoietic stem cell transplantation for haematological disorders on their websites. Officials clearly say that these therapies are currently investigational and must be conducted only within the scope of clinical trials. Dr. Alok Srivastava, Chairman, NAC-SCRT said, "Advertisements claiming to offer stem cell-based therapies other than Haematopoietic Stem Cell Transplantations for blood diseases … Continue reading →

Over the past decade, significant efforts have been made to develop stem cell-based therapies for difficult to treat diseases. Multipotent mesenchymal stromal cells, also referred to as mesenchymal stem cells (MSCs), appear to hold great promise in regards to a regenerative cell-based therapy for the treatment of these diseases. Currently, more than 200 clinical trials are underway worldwide exploring the use of MSCs for the treatment of a wide range of disorders including bone, cartilage and tendon damage, myocardial infarction, graft-versus-host disease, Crohns disease, diabetes, multiple sclerosis, critical limb ischemia and many others. MSCs were first identified by Friendenstein and colleagues as an adherent stromal cell population within the bone marrow with the ability to form clonogenic colonies in vitro. In regards to the basic biology associated with MSCs, there has been tremendous progress towards understanding this cell populations phenotype and function from a range of tissue sources. Despite enormous progress and an overall increased understanding of MSCs at the molecular and cellular level, several critical questions remain to be answered in regards to the use of these cells in therapeutic applications. Clinically, both autologous and allogenic approaches for the transplantation of MSCs are being explored. Several of the processing … Continue reading →

5 hours ago by Denis Paiste MIT biological engineering graduate student Frances Liu works with a spiral-shaped inertial microfluidic separation device for separating stem cell populations in the Laboratory for Material Chemomechanics at MIT. This device was adapted from previous designs to separate cells as a function of diameter. Liu also grows bone marrow-derived stem cells and studies how those stem cells release certain chemicals in response to mechanical interactions with materials in the surrounding environment. Credit: Denis Paiste/Materials Processing Center Researchers in MIT Associate Professor Krystyn J. Van Vliet's group last year showed that three biomechanical and biophysical markers could accurately identify the most desirable stem cells from a mixed group of bone marrow-derived cells. Now, MIT biological engineering graduate student Frances Liu is trying to advance that work by understanding how to alter the stem cells' physical environment to get them to produce the most desirable chemical output. The bone marrow cells secrete special chemicals called cytokines that are needed in the body to repair bone tissue, fat tissue, and connective tissue like cartilage. "These so-called factors that the cells produce are associated with those tissue growth functions and tissue repair functions," Van Vliet says. Liu grows bone … Continue reading →
