adultcellSydney:  Scientists have developed a new method for harvesting stem cells, which is less invasive and reduces side effects for donors.

The new method eliminates the need for the patient to take growth factor injections to increase cell numbers before a transplant.

The findings, published in the journal Nature Communications, showed that when these harvested cells are transplanted, they can replenish the entire bone marrow system.

Also the risks of side effects like bone pain and spleen enlargement, have been significantly reduced, the researchers explained.

“We’re looking forward to seeing patients benefit from this discovery,” said one of the researchers Peter Currie, professor at Monash University in Australia.

The method combines a newly discovered molecule (known as BOP), with an existing type of molecule (AMD3100) to mobilise the stem cells found in bone marrow out into the blood stream.

The team demonstrated that combining the two molecules directly impacts stem cells so they can be seen in the blood stream within an hour of a single dosage.

“Current treatment requires the patient to have growth factor injections for several days leading up to the procedure,” said Susie Nilsson, researcher at The Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia.

“Using the new method eliminates the need for this, meaning a procedure that once took days can be reduced to around an hour,” Nilsson added.

on an average 500 persons used to succumb everyday in the peak of Covid infection, as per the data. Health experts said that the mutated Coronavirus is losing its fierce characteristics as vaccination, better treatment facilities and awareness among the people have contributed to the lesser number of Covid deaths.

During the 4th and 6th of April two deaths were reported in Bengaluru, one in Gadag district on April 8, two deaths were reported from Belagavi and Vijayapura on April 30. The first Covid case was reported in the state in March 2020 and three Covid deaths were recorded in the month. In the following month 21 people became victims to the deadly virus, and May 2020 recorded 22 deaths. The death toll recorded everyday after May crossed three digits. However, the third wave, which started in January 2
