For more than a decade, Dr. Peter Zandstra, the Canada Research Chair in Stem Cell Bioengineering, has been working at the University of Toronto to increase the production of stem cells.十年多來，醫生彼得zandstra ，加拿大研究主持在幹細胞生物工程，一直在多倫多大��，以增加生產的幹細胞。 To do this, he has been applying engineering principles to stem cell research.要做��這一點，他一直在運用工程原理，以幹細胞研究。 Starting with computer models of stem cell growth and differentiation (the process by which a stem cell matures into its final form), Dr. Zandstra has moved on to develop more sophisticated culture methods that fine-tune the micro-environments to guide the generation of the different cells types that make up the mature cells in our tissues.從計算機模型的造血幹細胞生長和分化（這個過程，其中一個幹細胞的日趨成熟，進入了最後的形式） ，博士zandstra已轉移到開發���先進文化的方法微調的微環境，以引導代不同的細胞類型，彌補成熟細胞，在我們的組織中。

In November Japanese researchers showed that adult human and mouse skin cells could be reprogrammed into stem cells similar to embryonic stem cells, which can be transformed into any type of cell. 11月，日本研究顯示，成年人類和老鼠的皮膚細胞，可重組成成幹細胞類似胚胎幹細胞，這種細胞可以轉��成任何類型的細胞。 These cells, called induced pluripotent stem cells (iPS), has the potential to be a major step forward in using stem cells to cure a variety of diseases.這些細胞被��為誘導多能幹細胞（ IPS ）技術，有可能成為一個重大的一步，在利用幹細胞來治療各種疾病。 A major concern with using such stem cells (iPS) to treat disease has been the possibility that the retrovirus used to implant the cells might cause cancer, but now a group of Japanese scientists solved that problem.備���關注的主要問題是利用這種幹細胞（ IPS ）技術，以治療疾病已成為一種可能性，即逆轉錄病毒用來植入細胞，有可能導致癌症，但現在一組日本���學家解決了這個問題。

Japanese doctors, for the first time in the world, have used stem cells from liposuctioned fat to fix breast defects in women who had cancerous lumps removed from breasts.日本醫生，這是第一次，在世界上已使用幹細胞liposuctioned發修���乳房缺損的婦女，她們曾在癌腫塊免職乳房。 It may also be a way to augment healthy breasts without using artificial implants, potentially a dream come true for millions of women worldwide.它也可能是一個辦法，以充實���康的乳房沒有用人工植入物，可能是一種夢想終於成為現實，以百萬計的世界各地的婦女。
