Googling the terms "kidney organoid", "artificial kidney" etc. shows quite a huge amount of research papers regarding studies about kidney organoid synthesis from pluripotent stem cells and transplantation attempts.
But what I did not found (& my questions) are:
Are there any instances of successfully development and transplantation of kidney organoids in human beings? (yes/no)
If yes, then is it available as a therapeutic method? (yes/no)
