Biotechnologick\u00e1 spole\u010dnost chce vytvo\u0159it \u201esyntetick\u00e1\u201c lidsk\u00e1 embrya, ze kter\u00fdch by se mohly odeb\u00edrat org\u00e1ny, aby se usnadnily transplantace a l\u00e9\u010dily se stavy, jako je neplodnost, d\u011bdi\u010dn\u00e9 choroby a st\u00e1rnut\u00ed, \u0159\u00edkaj\u00ed v\u011bdci.<\/p>\n

P\u0159edpokl\u00e1d\u00e1 se, \u017ee je to poprv\u00e9, kdy bylo vytvo\u0159eno a uchov\u00e1no \u201esyntetick\u00e9\u201c embryo bez spermi\u00ed, vaj\u00ed\u010dek nebo d\u011blohy do tak pokro\u010dil\u00e9ho st\u00e1dia.<\/p>\n

Jacob Hanna, v\u00fdzkumn\u00edk z Weizmann Institute of Science v Rehovotu v Izraeli a zakladatel spole\u010dnosti Renewal Bio, chce nyn\u00ed stejnou technologii aplikovat na lidsk\u00e1 embrya.\u00a0V\u00fdsledky sv\u00e9 pr\u00e1ce publikoval v \u010dasopise Cell.<\/p>\n

\u201eEmbryo je nejlep\u0161\u00ed stroj na v\u00fdrobu org\u00e1n\u016f a nejlep\u0161\u00ed 3D biotisk\u00e1rna \u2013 sna\u017eili jsme se napodobit, co dok\u00e1\u017ee,\u201c \u0159ekl.<\/p>\n

„Jsme opravdu nad\u0161en\u00ed z t\u00e9to pr\u00e1ce a jej\u00edho dopadu.“<\/p>\n

Hanna pro Guardian \u0159ekla, \u017ee syntetick\u00e1 embrya nejsou \u201eskute\u010dn\u00e1\u201c, proto\u017ee nemaj\u00ed potenci\u00e1l vyvinout se ve skute\u010dn\u00e1 zv\u00ed\u0159ata.<\/p>\n
