Challenges associated with regenerative therapy/ cell replacement therapy in Diabetes

The current International Diabetes Federation (IDF) atlas indicate that every one in eleven (slowly approaching one in ten) adults are suffering from Diabetes. The true number is more alarming as a significant percentage of diabetic patients go undiagnosed. The main issue in diabetes is the dwindling beta cell population within the endocrine pancreas (islets), which significantly limits the biosynthesis and secretion of insulin. Scientists have been trying to come around this problem by exploring various means to generate new functional islets as there is a heavy limitation on donor (cadaveric) islets and all the other therapeutic drugs currently available in the market can only manage the diabetic condition, which is far from a cure. It is not that its impossible to replace the islets but there are a plethora of real time challenges involved in this process. I just wanted to take this opportunity and open a discussion that may help us understand these challenges more vividly...

Understanding Stem Cells

For my first post on my blog I wanted to address the understanding of Stem Cells. Stem cells being a niche area  even among biologist is a very specialized field which not many understand clearly and have a lot of misleading information. Hence, in this post I have tried to simplify the concept of Stem Cells for the layman and alike. A cell is basically the most fundamental unit that artistically constructs a human body. There are approximately 37 trillion cells making various distinct organ systems. There are about 200 different types of cells in each and everyone of us with distinct identity and function. One should not be surprised when we say that a cell has a unique identity and function for example our blood is red because of red blood cells, these cells carry oxygen to every part of our body and our bones are made of special cells called osteoblasts, which make them strong. Then what are stem cells? The word stem cell has been around since late 1800’s but the fi...
