Mukuedza kuita kuti kugadzirwa kwebiomaterial kuve nyore, vatsvakurudzi vanobva kuYunivhesiti yeCalifornia, Berkeley, vari kubatanidza 2D bioprinting, ruoko rwerobhoti rwegungano re3D, uye kupenya kwechando nenzira iyo rimwe zuva inogona kugonesa kudhindwa kwezvinyorwa zvipenyu uye kunyange nhengo dzose. Nekudhinda nhengo semapepa matete ematishu, wobva waomesa nechando uye nekuaisa zvakatevedzana, tekinoroji nyowani inovandudza kupona kwema biocell panguva yekudhinda uye kunotevera kuchengetedza.
Biomaterials inobata mukana wakakura weramangwana remushonga. Kudhinda kwe3D uchishandisa masero emurwere pachawo kuchabatsira kugadzira nhengo dzekutapurirana dzinonyatsoenderana uye dzisingakonzere kurambwa.
Dambudziko nderekuti nzira dzemazuva ano dzebioprinting dzinononoka uye hadzina kunyanyisa, sezvo masero anonetsekana kuti ararame maitiro ekudhinda pasina tembiricha yakasimba uye kutonga kwemakemikari. Kuchengeta uye kutakurwa kwematishu akadhindwa kunopawo mamwe matambudziko.
Kukunda matambudziko aya, timu yeBerkeley yakafunga kuenzanisa maitiro ekudhinda uye nekuipatsanura kuita matanho anotevedzana. Panzvimbo pekudhinda iyo nhengo yese kamwechete, matishu anodhindwa panguva imwe chete mu2D akaturikidzana, ayo anobva aiswa pasi neruoko rwerobhoti kugadzira yekupedzisira 3D chimiro.
Iyi nzira inotowedzera kukurumidza kuita, asi kuderedza kufa kwesero, zvidimbu zvinonyudzwa pakarepo mubhati ye cryogenic kuti iome. Sekureva kwechikwata, izvi zvinonyanya kukwenenzvera mamiriro ekupona kwezvinhu zvakadhindwa panguva yekuchengetedza uye yekufambisa.
"Parizvino, bioprinting inonyanya kushandiswa kugadzira mavhoriyamu madiki," anodaro Boris Rubinsky, purofesa weinjiniya. "Dambudziko ne 3D bioprinting nderekuti inononoka zvikuru, saka haugone kudhinda chero chinhu chikuru nokuti zvinhu zvehupenyu zvichafa panguva yaunenge wapedza. Chimwe chezvitsva zvedu ndechekuti tinoomesa ganda patinenge tichidhinda, kuitira kuti zvinhu zvipenyu zvichengetedzwe. "
Chikwata chinobvuma kuti nzira iyi yemhando dzakasiyana-siyana yekudhinda 3D haisi itsva, asi kushandiswa kwayo kune biomaterials kune zvitsva. Izvi zvinobvumira kuti zvidimbu zvidhindwe munzvimbo imwe uye zvozoendeswa kune imwe kunoungana.
Kupfuura kugadzira matishu uye nhengo, nzira iyi ine zvimwe zvinoshandiswa, senge mukugadzira chikafu chakaomeswa nechando pachiyero cheindasitiri.
Chidzidzo chacho chakabudiswa muna .
