器官再生是21世紀(jì)生命科學(xué)研究的焦點(diǎn)之一。由于具有幫助人類恢復(fù)因疾病、衰老或其它原因造成的器官損傷的潛力，器官再生在生物醫(yī)學(xué)領(lǐng)域一直具有很大的吸引力。低等脊椎生物（例如魚類、蠑螈等）具有極強(qiáng)的器官再生能力，他們可以完美地修復(fù)受損的心臟、大腦、脊髓及肢體；相比之下，高等哺乳動(dòng)物（包括人類）卻在進(jìn)化過程中丟失了這些能力。此外，器官再生能力在衰老過程中逐漸減弱，導(dǎo)致老年動(dòng)物生活質(zhì)量顯著下降。迄今為止，再生能力在進(jìn)化和衰老過程中是如何丟失的仍是生物學(xué)中未解的難題。借助具有顯著優(yōu)勢(shì)的非洲鳉魚（Nothobranchius furzeri）模型，我們實(shí)驗(yàn)室的主要研究興趣是鑒定賦予器官再生能力的核心分子機(jī)制，并以其為靶標(biāo)通過再生醫(yī)學(xué)手段探索人類受損器官的重建。
非洲鳉魚棲息在非洲東南部遭受季節(jié)性干旱的臨時(shí)水塘中。成年的非洲鳉魚僅在雨季池塘蓄水時(shí)才會(huì)出現(xiàn)。在干旱無水的季節(jié)，非洲鳉魚以被埋在泥中且處于滯育（diapause）或休眠狀態(tài)的胚胎形式存活，等待下一個(gè)雨季孵化并再次繁殖。強(qiáng)大的干旱選擇壓力使得該物種進(jìn)化出了獨(dú)有的特征，這些特征可以大大加速器官發(fā)育、再生及衰老相關(guān)的研究：1）生長(zhǎng)及性成熟速度快（野外14天即可性成熟，實(shí)驗(yàn)室條件下30-45天可性成熟，僅為斑馬魚所需時(shí)間的一半），極大地節(jié)省了遺傳操作和實(shí)驗(yàn)時(shí)間； 2）胚胎可以進(jìn)入滯育或休眠長(zhǎng)達(dá)兩年以上，使得遺傳品系的長(zhǎng)期保存方便且費(fèi)用低，無需像其他動(dòng)物模型需要長(zhǎng)期飼養(yǎng)成年動(dòng)物； 3）在實(shí)驗(yàn)室條件下衰老速度極快（平均壽命為4-6個(gè)月），是目前實(shí)驗(yàn)室可飼養(yǎng)的壽命最短的脊椎動(dòng)物模型； 4）由于早期胚胎發(fā)育緩慢， CRISPR/Cas9、Tol2介導(dǎo)的轉(zhuǎn)基因和PhiC31介導(dǎo)的位點(diǎn)特異性轉(zhuǎn)基因等遺傳操作效率高?？傊?，非洲鳉魚為成年動(dòng)物器官發(fā)育、再生和衰老研究帶來了傳統(tǒng)模型所缺乏的顯著優(yōu)勢(shì)和全新機(jī)遇。
Regeneration has long attracted biomedical interest because of the potential of replacing damaged organs with new ones. However, why some lower vertebrates (e.g., fish and salamanders) regenerate extensively while others such as mammals regenerate poorly is not well understood. Further, the ability to regenerate damaged organs displays progressive decline during aging, leading to reduced quality of life in old animals. How the regenerative capacities are lost during evolution and aging is still a long-standing question in biology. Powered with a new genetic model, the African killifish Nothobranchius furzeri, the Wang Lab is interested in identifying molecular mechanisms of regenerative capacities that can be targeted to help humans rebuild damaged and aged organs. Our current research will focus on, but not limited to, the following areas:
(1) The molecular basis of spinal cord regeneration.
(2) Evolution of regenerative capacities in vertebrates.
(3) Regeneration and Rejuvenation.
