Stem cell treatment could offer one-end-solution to Diabetes

Insulin-producing cells grown in the lab could provide a possible cure for the age-long disease (diabetes). Type 1 diabetes is an auto¬immune disease that wipes out insulin-producing pancreatic beta cells from the body and raises blood glucose to dangerously high levels. These high levels of Blood sugar level can be even fatal. Patients are being administered insulin and given other medications to maintain blood sugar level. To those who cannot maintain their blood sugar level, they are given beta-cell transplants but to tolerate beta cell transplants; patients have to take immunosuppressive drugs as well. A report by a research group at Harvard University tells us that they used insulin-producing cells derived from human embryonic stem cells (ESCs) and induced pluripotent stem cells to lower blood glucose levels...

Bats Carry Corona Virus. So Why Don’t They Get Sick?

A lot of viruses that has taken a toll on life, the ebola virus in Africa, The Nipah virus of Nipah and the most recent one corona virus that left china running helter skelter all seemed to have originated from bats. During the course of the virus epidemic in Wuhan where it was first detected, some Chinese researchers in Wuhan examined some patients affected in that area and then took samples of the virus. They did findings on the genetic sequence of the virus with other viruses that were known. The corona virus surprisingly had a 96% match with the horseshoe bats that are dominant in the southwest of china. The research findings were then published in a study on February, 2020. A virologist Vineet Menachery from...

A New Medical Device, in the Management of Complex Wounds

Because of the complex nature of wound healing process, an injury on the skin can pose several challenges and are likely pose complications especially when they are acute. They can as well deteriorate from acute to chronic conditions which will require external intervention best understood by a specialist physician to get the area affected by the wound under normalcy. The complexity of wound healing and research remains an ocean of knowledge that is continuously researched intensely to uncover depths of wound healing techniques and interventions. Hence, this report contains an introduction and details to the use of a new medical innovation called Gcells used primarily for the management of wounds in their different etiology. In a case where the process of wound healing seemed difficult, Gcells proved...

Knee replacement alternatives

One of the amputating surgeries in the field of medicine is a knee replacement. It involves removing the knee joint and replacing it with a modified prosthesis. However, several modifications of this surgery have been introduced into the high-powered world of surgery, including several alternatives for knee replacement. In this article, we are going to review the several modifications and knee replacement alternatives therein.  What is Knee Replacement? Knee replacement, also known as knee arthroplasty, is a surgical procedure that involves the amputation or cutting out of a knee joint, the bones reams by a doctor, especially due to accidents or joint ailments such as arthritis. When the bone is removed, it is then replaced with a prosthetic device. Knee replacement can be partial, where selected or...

Biodistribution, migration and homing of systemically applied mesenchymal stem/stromal cells

Biodistribution, migration and homing of systemically applied mesenchymal stem/stromal cells Abstract Mesenchymal stem/stromal cells (MSCs) are increasingly used as an intravenously applied cellular therapeutic. They were found to be potent in situations such as tissue repair or severe inflammation. Still, data are lacking with regard to the biodistribution of MSCs, their cellular or molecular target structures, and the mechanisms by which MSCs reach these targets. This review discusses current hypotheses for how MSCs can reach tissue sites. Both preclinical and clinical studies using MSCs applied intravenously or intra-arterially are discussed in the context of our current understanding of how MSCs might work in physiological and pathological situations. Background In the 1970s, Friedenstein and colleagues [1] first reported that locally applied culture-expanded populations of bone marrow stroma-derived fibroblastic cells remained...

The FDA Vs Stem Cell Treatments In The US

The FDA Vs Stem Cell Treatments In The US Stem cell therapy has become a popular type of treatment for a number of conditions, including to assist in the regeneration of injured tissue or diseases cells in the human body. This therapy is classified as regenerative medicine. Several advancements have already been made in this medical field, and many had experienced positive results when they underwent stem cell therapy to assist in the treatment of degenerative conditions. While stem cell therapy has been proven to provide an effective protocol in the recovery of stroke, neurological issues, and even to assist in repairing the damage that was dealt by a heart attack, recent reports have caused many to view these treatments in a negative perspective. This is due...

EXOSOMES

One major aims of regenerative medicine is to replace lost tissue with new cellular material or to improve the regeneration of damaged, malfunctioning, diseases tissue and organs using stem cell transplantation. In view of this,  the discovery of Extracellular vesicles (EVs) in the twentieth century have being considered as significant factors in inflammation and immune responses, antigen presentation, immunomodulation, coagulation, tissue regeneration, organ repair, cell-cell communication, senescence, proliferation and differentiation in the body [1].  Extracellular vesicles are believed to be involved in many biological processes and they can be modified to contain specific proteins, genetic lipids, and genetic materials including messenger RNA (mRNA), microRNA (mRNA), and other small non-coding RNAs, and genomic DNA (gDNA) from their progenitor cell. Extracellular vesicles are classified into two groups which...

MESENCHYMAL STEM CELLS

Over the last decade, cellular therapy has developed quickly at the level of in vitro and in vivo preclinical research and in clinical trials. Thus, one of the types of adult stem cells that have provided a great amount of interest in the field of regenerative medicine due to their unique biological properties is Mesenchymal stem cells (MSCs).  Mesenchymal stem cells (MSCs) are known to be multipotent stromal cells that can differentiate into a variety of cell types which include osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue). Furthermore, MSCs are responsible for tissue repair, growth, wound healing and cell substitution resulting from physiological or pathological causes; they have various therapeutic applications such as...
