Mukuedza kuita kuti kugadzirwa kwebiomaterials kusvike nyore, vaongorori vepaYunivhesiti yeCalifornia, Berkeley vari kubatanidza 2D bioprinting, irobhoti ruoko rwe3D assembly, uye kupenya kwechando nenzira inogona rimwe zuva kugonesa kudhindwa kwenyama mhenyu uye kunyange. nhengo dzese. Nekudhinda nhengo kuita mashizha matete ematishu, wobva waaomesa nechando nekuaisa zvakatevedzana, tekinoroji nyowani inovandudza kupona kwema biocell panguva yekudhinda uye panguva yekuzochengeta.
Biomaterials vane mukana wakakura wemushonga wenguva yemberi. Kudhinda kwe3D uchishandisa masero emurwere ega stem achabatsira kugadzira nhengo dzekutapurirana dzinonyatsoenderana uye dzisingakonzere kurambwa.
Dambudziko nderekuti nzira dzemazuva ano dzebioprinting dzinononoka uye hadzina kukwira zvakanyanya nekuti maseru ane nguva yakaoma kurarama mukudhinda pasina kudzora kwakasimba kwekushisa uye makemikari nharaunda. Zvakare, kuwedzera kuomarara kunoiswa nekumwe kuchengetedza uye kufambisa kwemachira akadhindwa.
Kukunda matambudziko aya, timu yeBerkeley yakafunga kuenzanisa maitiro ekudhinda uye nekuipatsanura mumatanho akatevedzana. Kureva kuti, pachinzvimbo chekudhinda nhengo yese kamwechete, matishu anodhindwa panguva imwe chete muXNUMXD akaturikidzana, ayo anozoiswa pasi neruoko rwerobhoti kugadzira yekupedzisira XNUMXD chimiro.
Iyi nzira inotokurumidza kukurumidza kuita, asi kuderedza kufa kwesero, zvidimbu zvinonyudzwa pakarepo mubhati ye cryogenic kuti iome. Sekureva kwechikwata, izvi zvinonyatso optimize mamiriro ekupona kwezvinhu zvakadhindwa panguva yekuchengetedza nekufambisa.
"Parizvino, bioprinting inonyanya kushandiswa kugadzira mavhoriyamu madiki," anodaro Boris Rubinsky, purofesa weinjiniya. βDambudziko re3D bioprinting nderekuti inononoka kuita, saka hauchakwanisa kudhinda chero chinhu chikuru nekuti zvinhu zvebiology zvinenge zvafa kana wapedza. Imwe yehunyanzvi hwedu ndeyekuti tinoomesa matishu patinenge tichidhinda, saka biological material inochengetedzwa. "
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.
Pamusoro pekugadzira matishu uye nhengo, nzira iyi ine zvimwe zvinoshandiswa, senge mukugadzirwa kwechikafu chakaomeswa nechando pachiyero cheindasitiri.
Chidzidzo chacho chakabudiswa muna .
