فئران نصف دماغها بشري.. ماذا يحدث داخل مختبرات جامعة ستانفورد؟

ما يعرفه ريفو عن الخبر

نجح باحثون في جامعة ستانفورد بزراعة خلايا دماغية بشرية داخل أدمغة فئران معدلة وراثيا.
تعدل الفئران وراثيا لتفتقر لأجزاء من القشرة المخية مما يوفر مساحة لنمو الأنسجة البشرية.
تساعد هذه التجربة في دراسة الاضطرابات الدماغية البشرية مثل الفصام والشلل الدماغي والخرف.
أظهرت الفئران المصابة بالأنسجة البشرية سلوكاً طبيعياً وأداءً مماثلاً للفئران العادية في الاختبارات.

طوّر باحثون من جامعة ستانفورد فئرانا تحتوي أدمغتها على خلايا بشرية حية نشأت من عضيات دماغية مزروعة، في نموذج تجريبي يهدف إلى تحسين دراسة اضطرابات عصبية لا يمكن تمثيلها بصورة كاملة في الفئران التقليدية
