The need for human organs far outpaces their availability, with more than 20 people dying each day waiting for a transplant. In particular, patients with end-stage liver disease (ESLD) have only one existing option for survival: liver transplantation. While many patients in the US have ESLD, only a few will receive a transplant. Remaining therapies for ESLD are palliative in nature and costly for hospitals. Our innovative cell-based therapy generates functional ectopic livers in ESLD patients, improving liver function, ameliorating related complications, and prolonging survival. A franchise model will establish LyGenesis Centers of Excellence near transplant-performing hospitals, increasing access to lifesaving therapy while also generating significant revenues, all at a cost-savings relative to transplantation.

Technology Description

When a liver is identified as not suitable for organ transplant, it will be transferred to a LyGenesis satellite to extract hepatocyte cells. At the same time, patients on the waiting list are contacted to come to the same LyGenesis location for preparation. In a minimally-invasive procedure, the cell suspension is transplanted into patients’ lymph nodes, where they survive, multiply, and ultimately grow into functional mini-livers. This technique has proven effective for treating liver disease in mice and pigs.


  • Can be used to treat ESLD patients who are not eligible for liver transplant due to complications and comorbidities
  • Increases availability of ESLD treatment
  • Uses livers deemed unsuitable for transplantation
  • Minimally-invasive


  • Patients who need a liver transplant, but are either are ineligible to receive one or too sick to wait on a long list
  • Underlying technology can be expanded to other organs (e.g., thymus or pancreas)

IP Status

US patent 9,125,891 was issued in September, 2015. A continuation application 14/810,064 was filed July, 2015. An US provisional patent application filed February, 2017.

Stage of Development

In collaboration with Mayo Clinic, we are currently evaluating another large animal model (Tyrosinemic pig). We are also planning for a pre-IND meeting with the FDA and a final pre-clinical large animal model.
