KidneyCell

bioKidneyCell is a startup within the Leonhardt Ventures Cal-X Stars Business Accelerator and Leonhardt’s Launchpads Utah focused on kidney regeneration.

The company utilizes bioelectric stimulation to control release of specific proteins on demand for specific regenerative purposes in sequence:

1. SDF-1 (stem cell homing factor – recruits a persons own stem cells to stimulated tissues).

2. VEGF (for new blood vessel growth).

3  IGF-1 (for DNA repair at the nucleus level). 

4. Follistatin (for muscle and tissue regeneration).

5. RANKL (for demineralization and tissue loosening when needed).

6. Hepatocyte Growth Factor  (tissue regeneration)

7. eNOS (for dilating blood vessels for increasing flow).

8.  Tropoelastin (increases elasticity of any tissues such as skin, arteries, aorta, heart and promotes healing of wounds). 

9. Activin A + B

10.  EGF Epidermal Growth Factor (regeneration)

In extreme cases we combine our regeneration microstimulator with an implantable, programmable, re-fillable stem cell/growth factor micro pump.

In cases of kidney cancer we have special signals to stop tumor cell division and blood supply followed by the above regeneration protocol.

Human amniotic fluid stem cell preconditioning improves their regenerative potential.

Abstract

Human amniotic fluid stem (hAFS) cells, a novel class of broadly multipotent stem cells that share characteristics of both embryonic and adult stem cells, have been regarded as promising candidate for cell therapy. Taking advantage by the well-established murine model of acute kidney injury (AKI), we studied the proregenerative effect of hAFS cells in immunodeficient mice injected with the nephrotoxic drug cisplatin. Infusion of hAFS cells in cisplatin mice improved renal function and limited tubular damage, although not to control level, and prolonged animal survival. Human AFS cells engrafted injured kidney predominantly in peritubular region without acquiring tubular epithelial markers. Human AFS cells exerted antiapoptotic effect, activated Akt, and stimulated proliferation of tubular cells possibly via local release of factors, including interleukin-6, vascular endothelial growth factor, and stromal cell-derived factor-1, which we documented in vitro to be produced by hAFS cells. The therapeutic potential of hAFS cells was enhanced by cell pretreatment with glial cell line-derived neurotrophic factor (GDNF), which markedly ameliorated renal function and tubular injury by increasing stem cell homing to the tubulointerstitial compartment. By in vitro studies, GDNF increased hAFS cell production of growth factors, motility, and expression of receptors involved in cell homing and survival. These findings indicate that hAFS cells can promote functional recovery and contribute to renal regeneration in AKI mice via local production of mitogenic and prosurvival factors. The effects of hAFS cells can be remarkably enhanced by GDNF preconditioning.

Stem cells derived from human amniotic fluid contribute to acute kidney injury recovery.

Abstract

Stem cells isolated from human amniotic fluid are gaining attention with regard to their therapeutic potential. In this work, we investigated whether these cells contribute to tubular regeneration after experimental acute kidney injury. Cells expressing stem cell markers with multidifferentiative potential were isolated from human amniotic fluid. The regenerative potential of human amniotic fluid stem cells was compared with that of bone marrow-derived human mesenchymal stem cells. We found that the intravenous injection of 3.5 × 10(5) human amniotic fluid stem cells into nonimmune-competent mice with glycerol-induced acute kidney injury was followed by rapid normalization of renal function compared with injection of mesenchymal stem cells. Both stem cell types showed enhanced tubular cell proliferation and reduced apoptosis. Mesenchymal stem cells were more efficient in inducing proliferation than amniotic fluid-derived stem cells, which, in contrast, were more antiapoptotic. Both cell types were found to accumulate within the peritubular capillaries and the interstitium, but amniotic fluid stem cells were more persistent than mesenchymal stem cells. In vitro experiments demonstrated that the two cell types produced different cytokines and growth factors, suggesting that a combination of different mediators is involved in their biological actions. These results suggest that the amniotic fluid-derived stem cells may improve renal regeneration in acute kidney injury, but they are not more effective than mesenchymal stem cells.
