Regenerative medicine is a promising field of science.

The increasing ability to engineer cells to our therapeutic advantage is creating a new type of platform for curing disease. Scientists have only begun scratching the surface, yet regenerative medicine -- the ability to use cells for therapeutic improvement -- will revolutionize healthcare. Here are a few of these incredible advancements.

Regeneration of the entire human epidermis using transgenic stem cells.

Regrowing Skin

The largest organ of the body is also one of the most accessible - the skin that surrounds and protects our entire body. Some of the earliest and most successful examples in regenerative medicine come from the growth of skin cells used as a treatment for a variety of skin-related diseases and injuries.

Spinal Cord Neuron Repair

The brain and its associated systems are arguably the most complex of the body. Neural cells have been created from stem cells in a number of pioneering studies with extremely promising results. From spinal cord injury to Parkinson's disease, the versatility of regenerative medicine strategies for nervous system repair are flourishing. Human trials are ongoing.

Giving Sight to the Blind

The eye is an especially attractive first target for stem cell-based regenerative medicine strategies. Researchers have created sheets of retinal cells from iPS cells and transplanted them into the eyes of a patient with promising results.

The 3D Printed Heart

One of the most exciting early-stage research avenues for regenerative medicine is the creation of entire new of organs custom built for individuals. Teams have recently 3D printed hearts using only human cells. It is achievements like these that are ushering in a new era of organ-level therapeutics.

Differences between young and old cells matter

Despite the incredible self-organizing, self-renewing nature of cells, their systems age and break down over time. Those effects are felt all the way up through tissues and organs. As a result of the effects of age, when we need our cells the most they are at their worst. Younger cells, we know, have the highest therapeutic capability. No wonder: none of the accumulated cellular damage exists to limit their potential.

Old Cells

Young Cells


When you pluck hair from your head, the follicles contain a valuable cluster of cells. Many of the most exciting regenerative medicine strategies rely on our ability to use growing cells and stem cells.

The Hair Follicle

Plucked hair follicles are an excellent, therapeutically-capable source of viable cells containing proliferative multipotent cells exceptionally capable of growing consistently in the lab. That makes them a valuable healthcare resource.

Viable Cells

This is the collection of cells dispersed throughout the hair follicle we know are viable: they're capable of growing further in culture. Some of these are multipotent stem cells, capable of direct conversion into skin and nervous system cells.

Non-Viable Cells

These are cells with signs of poor membrane integrity. It is common and normal for primary tissue samples to have numerous damaged cells. Before cryopreservation, Acorn ensures that you have enough viable cells.

Cellular Nuclei

Every plucked hair cell has a nucleus. This visualization technique allows us to see every cell in the population altogether.
