PROTEINS PRODUCED BY STEM CELLS, USED IN BONE REGENERATION

The loss of bone mass and the weakening of the bones are natural consequences of aging, but this process starts around the age of 30, so it’s not only the elderly that are at risk for falls and fractures due to bone resorption. Some of the factors that cause the decrease in bone mass density can be controlled, but others are out of one’s control. Smoking for example can be avoided, and one can practice strength exercises to keep their bones strong, but an inadequate intake of calcium, the use of asthma medications, as well as the changes in hormone levels that occur in older adults can speed up the weakening of bones. Also, this process is accelerated by an inadequate intake of vitamin D, the lack...

A Good Night's Sleep Protects Stem Cells From Premature Aging

If you’re one of those people who is really fond of their beauty sleep, or who never compromises when it comes to getting their full eight hours per night, now you have one more reason to make a full night's sleep a priority . A study by scientists at the German Cancer Research Center have found that while environmental stress can damage the DNA in adult hematopoietic stem cells, a good night’s sleep can keep these cells young, contributing to a youthful appearance and preventing cancer. Healthy sleep patterns lower the risk of DNA damage in stem cells  According to German researchers, under normal conditions a high number of different types of adult stem cells exists in a state of dormancy inside the human body, but they cannot...

Using Bone Marrow Stem Cells to Treat Heart Disease

What seemed an impossible medical challenge a few years ago might turn into a do-able task with the help of bone marrow stem cells. Several trials are testing the use of adult stem cells in heart disease, hoping to identify a viable solution for repairing the cardiac tissue damaged by heart attacks, coronary artery disease and other similar ailments. <h1>Obtaining cardiac muscle cells in the lab</h1> Despite the huge amount of information available out there and the numerous health programs that aim to prevent heart diseases, these conditions remain the most common cause of death in Europe, with heart attacks dominating the list. According to statistics, around 7 million people worldwide suffer from heart attacks each year, the damage being in lots of cases irreversible. Given the amazing...

The different types of stem cells and their current uses

Stem cells offer great potential for use in clinical applications thanks to their ability to specialize into different cell types and to renew themselves. Although some of them have limitations, stem cells are still an amazing resource for the medical world, as no other cell inside the human body has the ability to generate new cell types with a more specific function that the source. Stem cells can be considered the body’s raw building blocks, as all the other cells with specialized functions result from stem cells that divide and give birth to daughter cells. These cells, at their turn, divide or differentiate and become specialized, giving birth to muscle, bone, blood, brain or other specific cell types. The characteristics and applications of stem cells vary...
