HiPSCs can be grown indefinitely in the laboratory.

Remarkably, turning on just these four stem cell genes is sufficient to completely change the identity of the skin cells. Scientists use viruses to deliver the four stem cell genes, OCT4, SOX2, KLF4 and cMYC, into the skin cells. They cannot make brain cells and do not express brain genes. Skin cells ("fibroblasts") are only capable of growing in the laboratory for a few months. For the first time, using hiPSCs, we have enough live human brain cells afflicted by ASD to comprehensively study the structural and functional characteristics of these cells. These cells can be grown indefinitely in the laboratory, meaning that they can generate near limitless numbers of any cell type for scientific experiments. HiPSCs are "pluripotent" because they can be directed to give rise to every type of cell found in the human body.

Slowly, over the course of about one month, these stem cell genes turn the skin cells into stem cells. HiPSCs are "induced" because scientists generate them by turning on stem cell genes in skin cells. HiPSCs stands for "human induced pluripotent stem cells." These are a type of stem cell that scientists can generate in the laboratory from skin cells. We hope that understanding how brain cells with ASD are different will help us eventually identify drugs that help reverse these effects. Also, by taking skin samples from both patients with ASD and without, we can determine how the brain cells from the ASD patients are different. This means that from just a tiny skin sample from our ASD patients, we can generate limitless brain cells ("neurons") with which to study this disorder. In 2006, scientists in Japan discovered that skin cells could be changed ("reprogrammed") into stem cells that are capable of making every type of cell found in the body, including brain cells ("neurons"). Generating neurons in the lab from ASD patients It is only by generating hiPSCs from skin biopsies that scientists can now generate vast amounts of brain cells with which to study ASD. Brain stem cells do make brain cells, but they cannot be safely removed from patients with ASD. None of these stem cells can be used to make brain cells for our experiments. Skin stem cells can only make skin and hair. Intestinal stem cells can only make gut cells.

Hematopoietic stem cells can only make blood cells. The important thing to note about all of these adult stem cells is that they are lineage restricted. A third adult stem cell lives in the skin and is responsible for wound healing and hair growth.Īdult stem cells also reside in the hippocampus of the brain where they are believed to contribute to learning and memory. Another adult stem cell lives in the intestine and is responsible for replacing the lining of the gut every seven days. This is the type of stem cell transplanted in the treatment of leukemia. The best-described type of adult stem cell lives in the bone marrow and can differentiate into all the cell types of the blood (hematopoietic stem cells).

In the adult human body, several types of stem cells exist. Self-renewal describes the ability of one stem cell to make more of itself: one stem cell quickly becomes two, which becomes four and then eight, etc.ĭifferentiation describes the ability of a stem cell to mature into an entirely different cell type: it stops being a stem cell and starts being something else. All stem cells have two basic characteristics: they are capable of self-renewal and differentiation.
