Israel researcher creates those who give the first beating of world successfully in the lab already at present " miniature heart " , hopeful is used at repair heart tissue, benefit is counted with 1 million planHeart diseasePatient.
The person such as Professor Liaoer Gepusitan uses heart specialist of Israel engineering college first embryonic dry cell makes a heart cell, endodermis cell and into fiber cell 3 kinds of cells, next them embedded but in the structure of biology degradation. After a few weeks, these cells close for an organic whole, form the heart organization of one flake beating.
This cardiac muscle is not worth 1 square centimeter, bestrew imperceptible blood-vessel, become cardiac with compose complex organization is very similar. This is a scientist create a heart that includes all crucial cells successfully to organize first. Crucial is, they discovered one kind lets form cardiac to different type cell grows jointly and develop the method of action.
This one achievement learns in American heart " study circularly " after be being announced on the magazine, cause British expert intense echo. Professor Jeremy Pierxun says researcher of foundation of British heart disease: "We hope, the cardiac that because cardiac muscle straightens to die and be damaged,dry cell will make repair ' kit ' . We create a heart valve that is used at transplanting, hemal whole perhaps heart possibly even. We create a heart valve that is used at transplanting, hemal whole perhaps heart possibly even..
Nevertheless, current, the researcher can be bred only millions of cell, and the cardiac muscle loss that stalk of serious cardiac muscle causes to death needs about 1 billion cell to come repair.
Shulamite Liwenbeige says biology medicine engineer: "If we can enough large organization is patchy go up to human body heart, hold good blood to circulate with Yu Wei, so a lot of heart transplanting are done not have possibly necessary undertook. " replace a heart to transplant in the round inside short time still impossible, because the researcher returns need a few years,time ability innovation gives a complete heart. But the constituent section that develops larger area should by a definite date is not far, can undertake first human body experiment inside 10 years.
