KATHMANDU — In an incredible development that could possibly go a long way in medical practices, scientists in California are working on a way to reduce organ transplants and rejections: Growing embryos in sheep and pigs containing human patients’ cells.
In a transplant breakthrough, scientists at the University of California said they have achieved sheep embryos in which around one in every 10,000 cells was human, according to UPI report.
The researchers presented preliminary findings Saturday at the American Association for the Advancement of Science’s annual meeting in Austin, Texas.
The new finding paves way for genetically tailoring the organs to be compatible with the immune system of the patient receiving them, thus removing the possibility of rejection, the report said.
The hybrid embryos contain both human and sheep cells and were created in an early step toward growing human organs in farm animals before transplanting them into patients.
Last year, the same researchers introduced human stem cells into early pig embryos, producing embryos with about one in every 100,000 cells being human.
The experiment began with Hiro Nakauchi, from the University of Tokyo, who grew a mouse with a rat pancreas and a rat with a mouse pancreas.
When cells from the rat-grown mouse pancreas were transplanted into a diabetic mouse, they made enough insulin to cure the condition without being rejected.
Mice and rats are different types of rodents with the former having thin slightly hairy tails, while rats have thicker hairless scaly tails.
“The next step was to move into large animals,” Nakauchi said. Since this was prohibited in Japan, he moved to the Stanford University in the US.
Nakauchi’s rodent work has demonstrated that you can “grow organs in a different species and cure a disease without [suppressing the immune system],” added co-researcher Pablo Ross, Professor at from the University of California, Davis.
“We are working together to translate the technology into humans, to solve the terrible shortage of organs for transplantation. In the US, 20 people die every day because they cannot get the organs they need,” Ross explained.

Closed session of NC mahasamiti meeting kicks off
KATHMANDU- The closed session of the Nepali Congress mahasamiti meeting kicked off this morning.
In the closed session, General Secretary has presented the organizational report while Treasurer Sitadevi Yadav the account report, and Joint General Secretary Dr Prakash Sharan Mahat the economic proposal. The mahasamiti members are to discuss thoroughly on these three documents today.
NC Spokesperson Bishwo Prakash Sharma informed the National News Agency (RSS) that the party statute would be passed based on the views of the attending members.
However, the consensus is eluding on the draft amendment of the statute. After the central committee forges consensus, it would be presented before the mahasamiti meeting.
More than 1,700 representatives including members and observers are attending the mega meeting. The mega meeting of the party is to continue for two more days.Follow @gorkhapost
