विज्ञान की नई खोज- किमेरा भ्रूण(chimera embryos -growing spare human organs in other animals)

Scientists Create First Human-Pig Chimeric Embryos  – Researchers may one day overcome the problem of organ shortages for transplantation by growing spare human organs in other animals. A group led by scientists at the Salk Institute for Biological Studies has taken the first big step toward making this a reality  (on January 26 , 2017 ) in Cell, they report having grown the first human-pig chimeric embryos.

हर साल दुनिया में हजारों लोगों की मृत्यु मानव अंगों की कमी की वजह से होती हैं। लगभग हर दस मिनट में  एक न एक व्यक्ति  अंग प्रत्यारोपण के लिए  प्रतीक्षा सूची में जोड़ा जाता है और हर दिन, उस सूची में 22 लोगों को अंग की जरूरत पूरी नहीं होने से  मर जाते हैं।

कैलिफोर्निया में सॉल्‍क इंस्‍टीट्यूट फोर बायलॉजिकल स्‍टडीज, अमेरिका के वैज्ञानिकों ने  सुअरों के अंदर इंसानी अंग उगाने के प्रयोग कि‍या हैं । 26 जनवरी, २०१७ को   वैज्ञानिकों ने एक उल्लेखनीय घोषणा की ।  वे पहली बार सफल मानव पशु संकर बनाने में सफल हुए हैं। पहला मानव-सुअर संकर भ्रूण प्रयोगशाला में बनाया गया है।  अभी प्रयोग शुरुआती दौर में है। पर वैज्ञानिकों  विश्वास है कि एक दिन प्रयोगशाला में मानव अंग  विकसित  अौर प्रत्यारोपित किये जा सकगें।

इस प्रक्रिया के तहत मरीज के ही शरीर की मूल कोशिकाओं को सूअर  के शरीर में विकसित किया जा सकेगा। एक बार अंगों के विकसित हो जाने पर उसे मरीज के शरीर में ट्रांसप्लांट  किया जा सकता है। ये अंग मरीज की अपनी कोशिकाओं से विकसित होने केी वजह से शरीर द्वारा स्वीकार किए जाने की ज्यादा संभावना रहेगी ।

    1. यह research मुझे भी बङी अनोखी अौर महत्वपूर्ण लगी। आज organ failure बहुत बङी समस्या है।


  1. Very nice post. I simply stumbled upon your
    blog and wanted to mention that I’ve really loved browsing your
    weblog posts. In any case I will be subscribing on your feed and I

  3. This is the perfect site for everyone who really wants to understand this topic.
    You realize so much its almost tough to argue with you (not that
    I really would want to?HaHa). You definitely put
    a brand new spin on a subject that’s been discussed for years.

  4. You really make it seem so easy with your presentation but I find this matter to
    be actually something which I think I would never understand.
    It seems too complicated and extremely broad for me. I’m looking forward
    for your next post, I’ll try to get the hang of it!


  5. A motivating discussion is worth comment. I do think that you ought to write more on this
    topic, it may not be a taboo matter but typically people do not discuss these subjects.

    To the next! Best wishes!!

    and located that it’s truly informative. I’m gonna
    be careful for brussels. I will be grateful for those who
