It’s – Almost – Not Science Fiction Anymore!

If you look on the blogroll to the right, below the calendar, you’ll see the American Society of Nephrology included.  Personally, I’m thankful this organization was one of the first to acknowledge my blog. As a Chronic Kidney Disease patient, I’m thankful they exist to keep us updated on the latest findings about our disease (among other things). This is the largest organization to deal with kidney disease.  That would explain why I periodically look at their site to see if there’s anything to share with early stage patients.  On Wednesday, their tweet referred to an article that could make kidney patients who are dreading eventual dialysis cry – for joy, that is.  I freely admit I am one of those.

Could patients’ own kidney cells cure kidney disease?

Reprogrammed kidney cells could make transplants and dialysis things of the past

  • Patients’ own kidney cells can be reprogrammed and used as therapy against kidney disease
  • Cells can easily be collected from the urine
  • 88,000 patients are waiting for a kidney transplant in the United States, and they wait for an average of 3 to 5 years

Washington, DC (July 27, 2011) — Approximately 60 million people across the globe have chronic kidney disease, and many will need dialysis or a transplant. Breakthrough research published in the Journal of the American Society Nephrology  (JASN) indicates that patients’ own kidney cells can be gathered and reprogrammed.  Reprogramming patients’ kidney cells could mean that in the future, fewer patients with kidney disease would require complicated, expensive procedures that affect their quality of life.

In the first study, Sharon Ricardo, PhD (Monash University, in Clayton, Australia) and her colleagues took cells from an individual’s kidney and coaxed them to become progenitor cells, allowing the immature cells to form any type in the kidney. Specifically, they inserted several key reprogramming genes into the renal cells that made them capable of forming other cells.

In a second study, Miguel Esteban, MD, PhD (Chinese Academy of Sciences, in Guangzhou, China) and his colleagues found that kidney cells collected from a patient’s urine can also be reprogrammed in this way. Using cells from urine allows a technology easy to implement in a clinic setting. Even better, the urine cells could be frozen and later thawed before they were manipulated.

If researchers can expand the reprogrammed cells—called induced pluripotent stem cells (iPSCs)—and return them to the patient, these IPSCs may restore the health and vitality of the kidneys. In addition to providing a potentially curative therapy for patients, the breakthroughs might also help investigators to study the causes of kidney disease and to screen new drugs that could be used to treat them.

In an accompanying editorial, Ian Rogers, PhD (Mount Sinai Hospital, in Toronto, Ontario, Canada) noted that “together, these two articles
demonstrate the feasibility of using kidney cells as a source of iPSCs, and efficient production of adult iPSCs from urine means that cells can
be collected at any time.”

Just as exciting, the ease of collection and high frequency of reprogramming described in these articles may help improve future therapies in many other areas of medicine.

I am thrilled whenever I find new information that gives me hope.  This is a thrilling day.

Until Tuesday,
