Ngoku kunokwenzeka ukuvelisa ii-corneas eziprintiweyo ze-3D

I-3D corneas eprintiweyo

Kukhuphelo lwamva nje olukhutshwe yi IZiko loPhando lwezoBiomedical lweSibhedlele iLa Paz Kwaziswa ukuba eli ziko likwazile ukuphuhlisa, ngeendlela ezintsonkothileyo zokuphanda ngeeseli, indlela entsha ethi, ngokusebenzisa izinto zebhayoloji kunye neeseli zesigulana, kuya kwenzeka Yenza ii-corneas ezifanayo ngokupheleleyo nezo zinikelwa ngumshicileli we-3D.

Njengoko sele kuphawuliwe kwiziko lophando ngokwalo, injongo yale projekthi kukwenza iicorneas zokuqala ukusetyenziswa kweklinikhi kwiminyaka emi-5 kunye nokuzivelisa yenziwe ngokukodwa kwaye yenziwe yaba yeyakho ngokupheleleyo kwisigulana ngasinye ingaphelanga iveki.

Abaphandi abavela kwiZiko loPhando lweBiomedical Institute of Hospital La Paz balawula ukuphuhlisa indlela entsha yokwenza i-3D-eprintwe i-corneas

Enkosi ngombono wenoveli, iprojekthi ikhethwe yi Isiseko soTshintsho kunye nokuLindeleka kwezeMpilo eSpain (Fipse) ngaphakathi kwesakhelo senkqubo ye-Idea2 yeLizwe jikelele ephuhliswe liziko lobugcisa laseMassachusetts (MIT).

Njengoko kuchazwe yedwa Isiseko soTshintsho kunye nokuLindeleka kwezeMpilo eSpain Kwiphepha layo lokushicilela, le projekthi iphonononga iindlela ezahlukeneyo zokwenza i-collagen polymeric extracellular matrix ekwaziyo ukulinganisa ii-corneas zabantu kunye ne-biomimetic corneal stroma ekufuneka ikwazi ukutshintsha imfuno yabaxhasi babantu.

Iiseli zesigulana se-mesenchymal stem cells ziya kuprintwa nge-3D kwimatrix esele ichaziwe, ngaloo ndlela zivelise i-corneas eyenziwe yenzelwe ukuphendula abantu abafuna ukufakelwa i-corneal nokubuyisela umbono wabo. Ngaphandle kwamathandabuzo, oku kufumanisa kunye nokufezekiswa kwetekhnoloji kunokuba linyathelo elikhulu ekuboneleleni ngentlalo-ntle enkulu kubantu abaninzi, hayi ilize namhlanje emhlabeni kukho ngaphezulu kwe-10 yezigidi zabantu abangaboniyo emhlabeni ngenxa yesi sifo kwii-corneas zabo.
