How do adult stem cells work? In healthy tissue the adult stem cell population lies dormant. Dormant stem cells are activated by external trauma signals, which trigger patterns of gene expression and protein biosynthesis, thus activating the stem cells to multiply and...

Simple diagram that shows the development of different blood cells from hematopoietic stem cell to mature cells. From Wikipedia. All blood cells arise from the common hematopoietic stem cell and are classified into two lineages: lymphoid cells (B-, T- and Natural...

When using stem cells for regenerative therapies, there are a few approaches that can be taken. Donor cells have issues with matching and immune rejection. Autologous stem cells transplants skirt rejection issues, but both strategies still face challenges associated...

For centuries, “snake oil salesmen” have used cleverly crafted acts to peddle fake medicines. The modern-day version of the medical conman has zeroed on stem cells, selling treatments with unproven effects and unknown risks. Using online marketing campaigns, stem...

The UK-based Motor Neurone Disease Association has recently funded a £800,000 ($1.2 million) program to study motor neurons derived from the skin cells of amyotrophic lateral sclerosis (ALS) patients with rare, disease-causing mutations in the gene TARBP. Although the...

Part one in a series looking at the processes involved in the most clinically applied form of stem cell therapy: hematopoietic stem cell transplantation Leukocytes, or white blood cells (WBCs), are an essential part of the immune system. Produced in the bone marrow,...

The potential gains from stem cell research are unlimited; stem cells could be used to replace degenerated cells and tissue in the human body. However, the large scale implementation of stem cell therapy to a clinical setting will require the establishment of a...

Amyotrophic lateral sclerosis (ALS), known as Lou Gehrig’s Disease and motor neuron disease (MND), is a progressive neuromuscular disease that attacks nerve cells in the brain and spinal cord. As these neurons slowly waste away, they become unable to transmit signals...
