据媒体报道,近日,美国研究人员培育出一种与老鼠大脑功能和结构极其相似的三维大脑样组织,其在实验室里的存活时间超过了两个月。用丝蛋白制成的同心环状支架,可模拟新皮质的6个分层。每一环被染成了不同颜色,并被分别填充了神经元塔夫茨大学研究人员报告说,培养三维大脑样组织的关键在于一种由蚕丝蛋白和胶原蛋白凝胶组成的复合结构,其中蚕丝蛋白被制 According to media reports, U.S. researchers have recently developed a three-dimensional brain-like tissue that closely resembles the brain’s function and structure in mice and has lived in the laboratory for more than two months. Concentric ring scaffolds made with silk protein simulate 6 layers of neocortex. Each ring is dyed in a different color and filled with neurons respectively. Tufts University researchers report that the key to developing 3D brain-like tissue is a composite structure consisting of fibroin and collagen gels, of which Silk protein is made
