Ekugcineni ... ikhambi lokwelapha ukuhluleka kwenhliziyo

Ukuhlola kwesayensi yaseBrithani kwaphumelela ekusebenziseni indlela entsha yokujova ama-stem cells emsipha wenhliziyo.

Ngemva kwemizamo yangaphambilini yokuvuselela amangqamuzana enhliziyo kusetshenziswa ama-stem cells antekenteke ngenxa yokungakwazi ukuzivumelanisa nendawo yawo entsha, ithimba labacwaningi abavela e-University College London likwazile ukuqhamuka nendlela yokugcinwa kwama-stem cells ephila isikhathi eside. inhliziyo ngokuqala ngokuyifakela kuma-miniature sphere Ngokusho kweBritish "Daily Mail".

Abacwaningi babike ukuthi ubukhulu bamabhola amancane busho ukuthi bangajovwa emisipha yenhliziyo, indlela ehlolwe ngempumelelo kumagundane futhi inesithembiso sokwelashwa kwenhliziyo, lapho inhliziyo ingakwazi ukupompa igazi ngendlela efanele kulo lonke. umzimba.

isitayela esithembisayo

Ososayensi nabo banethemba lokuvivinya ukwelashwa kwabantu phakathi neminyaka eyishumi, njengoba uDkt. Daniel Stoke we-University College London ecabange ukuthi ubuchwepheshe obusha buyindlela entsha yokuqinisekisa ukuthi amangqamuzana ajovwe enhliziyweni asebenza ngendlela okufanele asebenze ngayo.

USolwazi Metin Avkiran, weBritish Heart Foundation, uthe lolu cwaningo olusha luwuhlelo oluthembisayo lokulethwa olunganikeza amangqamuzana enhliziyo atholakala kuma-stem cells ithuba elingcono kakhulu lokwelapha izinhliziyo ezigulayo.

Amaseli e-stem angabuye aphenduke abe yizo zonke ezinye izinhlobo zamaseli futhi asetshenziswe ekufakeni umnkantsha wethambo nezinye izindlela zokwelapha.

Ukwelashwa okungcono kweziguli zenhliziyo

UDkt Annalisa Pitney, wase-University College London, uthe ngaphezu kokwenza imijovo yenhliziyo, ukuthuthukiswa kwala ma-microsphere wukulandelela ama-stem cell ukuze avele ajove endaweni ethize yenhliziyo elimale.

Kuyaphawuleka ukuthi izehlakalo zokwehluleka kwenhliziyo ziyisifo izigidi zabantu ezihlushwa umhlaba wonke ngaphandle kokwelashwa okuqondile okuqeda le nhlekelele.

Ngokuzayo, le ndlela entsha kulindeleke ukuthi iqinisekise ukuthi odokotela benhliziyo bahlonyiswe ngezixazululo eziningi zokuhlinzeka ngokwelashwa okungcono kakhulu kweziguli zabo.
