相比出生后,胎儿也许更适合干细胞治疗,因为排异反应少,受到疾病的伤害也少。于是,瑞典科学家第一次用干细胞来治疗胎儿的脆骨症。还没出生就患病脆骨症,又名成骨不全,是一种基因突变造成的罕见病。在我国,脆骨症患者被称作瓷娃娃,因为他们轻易就会发生骨折,脆弱得像瓷人。瓷娃娃制造胶原蛋白的基因有缺陷,骨缺少了这种有韧性的物质就会变得十分脆弱。更悲惨的是,瓷娃娃在还是胎儿的时候就有可能在母 Compared to after birth, the fetus may be more suitable for stem cell therapy, because fewer rejection, less damage by the disease. So, for the first time, Swedish scientists used stem cells to treat fetal fragility. Not born ill diseased brittle disease, also known as osteogenesis imperfecta, is a rare disease caused by genetic mutations. In China, people with brittle bone are called porcelain dolls, because they easily fracture, fragile as porcelain. Porcelain doll collagen production of genetic defects, the lack of such a tough bone material will become very fragile. Even more tragic is that porcelain doll in the fetus when it is possible in the mother
