Implantation of fetal pig lung fragments into adult rat lung parenchyma-search for a possibility of transbronchial delivery with a bronchoscope-

根据我们在大鼠胎肺组织移植的结果，将胎猪肺组织解剖并切成非常细小的碎片植入成年猪肺实质中。移植的胎肺组织在成人肺内存活和成熟。在同种异体联合移植的情况下，需要免疫抑制以保持植入的问题。经支气管镜可将胎肺组织送入肺泡腔，但在开胸情况下，经胸膜外植入的胎肺组织并不比胸膜植入法更容易存活。

Depending on our results of fetal lung tissue transplantation in the rat, fetal pig lung tissue which were dissected and cut into very fine pieces implanted into adult pig lung parenchyma. The implanted fetal lung tissues lived and matured in adult lungs. Under the situation of allograft combination, immunosuppression was needed to keep the implanted issues. Fetal lung tissues could be delivered into alveolar space using a bronchoscope, however, fetal lung tissues delivered by this method did not survived easier than by the method of transpleural implantation under thoracotomy.
