Claim 14:
15. A producing method of a proximal tubule cell construct comprising the steps of:
producing a decellularized substance derived from a mammalian kidney tissue;
extracting and preparing human umbilical vascular endothelial cells (HUVECs) and renal proximal tubular epithelial cells (RPTECs) from a living kidney tissue;
producing a first bioink comprising the decellularized material and the HUVECs;
producing a second bioink comprising the decellularized material and the RPTECs;
printing a vascular tubule construct using the first bioink; and
printing a proximal tubule construct using the second bioink,
wherein the printing of the vascular tubule construct and the printing of the proximal tubule construct are performed while the vascular tubule construct and the proximal tubule construct are at least partially in contact with each other.
