♡라엘사이언스♡ 인공장기생산에 획기적인 발전

[하모니]

요약:블루

예루살렘의 헤브류 대학의 치의학 연구원들이
생물학적인 인공장기 생산에 획기적인 전기를 마련했다.

인공장기 생산에서 가장 어려운 부분이 혈관생성으로
이들은 성체 간세포에서 혈관세포를 생산해 내는데 성공했다.

이 기술로 이들은 체외에서 골격조직과 혈관조직을 만들어내는
데 성공했다. 그들이 만들어낸 것은 인공골격 뿐이지만
이 기술은 모든 장기에 응용될 수 있다.

Breakthrough in creating bio-artificial organs at Hebrew University-Hadassah Dental School

Jerusalem, July 2 ?Today people often must wait for months when they need an organ transplant. In the future, they may be able to simply give a tissue sample and then wait a week or two as the sample is used to custom-build the necessary organ, thanks to research conducted by Hebrew University Ph.D. candidate Gadi Pelled, DMD. He received the prestigious Kaye Award this year for his work.

Dr. Pelled explained that one of the major difficulties in creating bio-artificial organs is creating a network of blood vessels in the organ that can connect to those in the body. Working under the guidance of Associate Professor Dan Gazit, Dr. Pelled managed to grow and then combine cells from blood vessels and genetically engineered adult stem cells to create a three-dimensional bio-artificial bone in the lab.

Though Dr. Pelled only has conducted research related to bio-artificial bone thus far, the method he invented can be applied to any tissue that has blood vessels, he said.

Dr. Pelled's technology has been exclusively licensed to SBT, a start-up company founded by the Yissum Research Development Company of the Hebrew University and Prof. Gazit. SBT's mission is the engineering of skeletal tissue and vascular tissues, including bone, cartilage, tendon, ligament, and blood vessels. SBT is well positioned to be a leader in the field. It has developed a unique proprietary biological technology, targeted at the use of ex-vivo (outside the body) tissue engineering, for the generation of biological bone, cartilage, ligament/tendon, and small-diameter blood vessels grafts and methods for treating diabetes, cardiovascular diseases and stroke. SBT has also developed a novel ex-vivo three-dimensional system for drug screening.

This research project was performed with another Kaye award winner, Yossi Gafni. Mr. Gafni is a graduate student conducting research in Prof. Gazit's lab. His main focus is vascular tissue engineering.

Dr. Pelled, 33, completed a D.M.D. in dental medicine at the Hebrew University in 1995 and, after working as a dentist for several years, returned to pursue a Ph.D. in biotechnology. Dr. Pelled, who lives in Rishon Lezion, is married and has two children.

The Kaye Innovation Awards at the Hebrew University have been awarded annually since 1994. Isaac Kaye of England, a prominent industrialist in the pharmaceutical industry, established the awards to encourage faculty, staff, and students of the University to develop innovative methods and inventions with good commercial potential which will benefit the University and society.
