Hinduism is the Only Dharma

Hinduism is the Only Dharma in this multiverse comprising of Science & Quantum Physics.

Josh Schrei helped me understand G-O-D (Generator-Operator-Destroyer) concept of the divine that is so pervasive in the Vedic tradition/experience. Quantum Theology by Diarmuid O'Murchu and Josh Schrei article compliments the spiritual implications of the new physics. Thanks so much Josh Schrei.

Researchers show sperm stem cells can help treat diabetes

Researchers show sperm stem cells can help treat diabetes


Men with insulin-dependent diabetes may one day have their condition treated using cells from their testicles.
Scientists have succeeded in transforming sperm stem cells into the pancreatic cells that generate insulin.

Tests on diabetic mice showed the beta islet cells could produce enough of the vital hormone to start reversing their disease.

Researchers hope in future it may be possible to treat men with Type-1 diabetes with islet cells grown from their own spermatogonial stem cells (SSCs).

Because the therapeutic cells would originate from their own bodies, they would not be rejected by the immune system.

However, a leading charity warned against raising hopes of a cure prematurely.

Type-1 diabetes, which affects about 300,000 people in the UK, is an auto-immune disease in which insulin-producing cells in the pancreas are gradually destroyed.

Doctors have investigated replacing the lost cells with transplants from deceased patients, but there are few suitable donors and rejection is a serious problem.

Experiments with "induced pluripotent" stem (IPS) cells - ordinary cells reprogrammed to have the properties of stem cells from embryos - have also met with obstacles. The technique produces tumours in mice and involves inserting genes, which can be harmful.

Instead of IPS cells, the new research focused on SSCs, early precursors of sperm cells found in the testes. They come ready-equipped with the genes necessary for them to morph into "pluripotent" cells - cells capable of launching themselves on many different development paths.

A US team led by Ian Gallicano, from Georgetown University Medical Centre in Washington DC, took the SSCs from the testes of dead human donors.

One gram of tissue was used to grow about a million stem cells with the biological characteristics of beta islet cells. These were then transplanted into the backs of immune-deficient diabetic mice, where they secreted insulin.

In about a week the animals' blood glucose levels had been reduced, showing that enough insulin was being produced to tackle the excess sugar load characteristic of diabetes.

"No stem cells, adult or embryonic, have been induced to secrete enough insulin yet to cure diabetes in humans, but we know SSCs have the potential to do what we want them to do, and we know how to improve their yield," said Dr Gallicano.

The findings were presented at the annual meeting of the American Society of Cell Biology in Philadelphia.
