A newly launched startup is constructing upon improvements developed over a number of years on the Wyss Institute for Biologically Impressed Engineering at Harvard College, Harvard John A. Paulson College of Engineering & Utilized Sciences (SEAS), and Brigham and Ladies’s Hospital (Brigham) to engineer useful kidney tissue for renal restore and alternative remedy.
Jennifer Lewis’ and Ryuji Morizane’s groups discovered beforehand that culturing kidney organoids below fluid stream causes endogenous endothelial progenitors to create extra mature vascular networks which pervade the entire organoid and work together with epithelial compartments. This discovering presents a crucial advance towards the long run improvement of recent approaches by Trestle to deal with continual kidney illness utilizing 3D bioprinting and stem cell-based tissue engineering.

San Diego-based Trestle Biotherapeutics has been granted a license, by Harvard’s Workplace of Know-how Growth (OTD), to commercialize a collection of stem cell- and 3D bioprinting-based kidney regenerative medication applied sciences developed at Harvard’s Wyss Institute, SEAS, and Brigham. Based in 2020, Trestle is led by Ben Shepherd, Ph.D. and Alice Chen, Ph.D., each with deep expertise in business efforts targeted in stem cell biology, tissue engineering, regenerative medication, and 3D bioprinting.
The shortage of transplantable kidney tissues and complete organs is a gigantic problem within the remedy of continual and end-stage kidney illness. As of 2021, within the US alone, there are greater than 550,000 dialysis-dependent sufferers and 100,000 sufferers ready for kidney transplants, but solely about 20,000 transplants are carried out every year, with practically 5,000 sufferers on ready lists dying every year with out receiving a transplant . Past kidney failure, there are greater than 60 genetic illnesses that immediately or not directly have an effect on renal perform, a lot of which can’t be appropriately handled with current therapeutics.
The foundational expertise was pioneered by researchers within the lab of Jennifer Lewis, Sc.D., who’s a Wyss Core College member, main the Wyss Institute’s Organ Engineering Initiative, the Hansjörg Wyss Professor of Biologically Impressed Engineering at Harvard SEAS, and a Affiliated College member of the Harvard Stem Cell Institute (HSCI). Lewis’ lab has collaborated with a number of clinicians, together with Joseph Bonventre, MD, Ph.D., Chief of the Division of Renal Medication and Founding Chief of the Engineering in Medication Division on the Brigham, and Ryuji Morizane, MD, Ph.D. , who’s now an Assistant Professor on the Massachusetts Basic Hospital (MGH) and Harvard Medical College (HMS), an Affiliated College member at Harvard Stem Cell Institute, and a Visiting Scholar on the Wyss Institute.
We’re very excited to convey the biofabrication and stem cell biology applied sciences developed within the Lewis and Morizane labs into what we’re constructing at Trestle. The groups at Harvard, Wyss, and the Brigham have a famend monitor file in translational innovation, and we’re thrilled with the chance to hold their work ahead for sufferers’ profit.”
Shepherd, CEO, Trestle
“Greater than a dozen members of my lab contributed to the improvements in tissue engineering which have created this expertise platform,” mentioned Lewis. “Most just lately, we developed a brand new biomanufacturing methodology, referred to as sacrificial writing in useful tissue (SWIFT), that permits the fabrication of vascularized kidney tissues. I am happy that Trestle has now launched to translate this sturdy expertise to deal with the rising want for kidney tissues and organs.”
Supported partially by Harvard OTD’s Bodily Sciences & Engineering Accelerator, and later by the Wyss Institute’s Organ Engineering Initiative, Lewis and her colleagues on the Wyss and SEAS made seminal contributions to the sector of multimaterial 3D bioprinting. Utilizing their platform expertise, Lewis and her collaborators have created 3D kidney-on-chip fashions for drug screening and illness modeling and have established foundational expertise for quickly producing vascularized kidney tissue at scale for restore and regeneration.
Central to the success of this strategy was a collaboration between the Lewis Lab and researchers on the Brigham. Morizane, Bonventre, and different clinicians had developed a technique for producing kidney organoids from human pluripotent stem cells in vitro. These tissue constructs contained giant numbers of well-organized nephrons, however lacked a vascular community that could possibly be perfused with blood. This deficiency was overcome by subjecting the organoids to the stream of fluids on bioengineered units. In a collaborative effort revealed in Nature Strategies, the joint crew succeeded in producing vascularized kidney organoids with enhanced nephron maturation in vitro.
“We had been capable of display for the primary time a extra superior kidney structure and performance in human kidney organoids, which is vital for creating tissue segments to be used in drug testing and illness modeling and, finally, in vivo therapeutics,” mentioned Morizane. Lewis and Morizane are members of Trestle Biotherapeutics’ scientific advisory board.
By combining these approaches with further options for cell and tissue manufacturing, inner experience in stem cell and kidney organoid biology, and the commercialization of 3D bioprinted human tissues, the crew at Trestle will work in direction of its purpose of making a brand new normal of care possibility for sufferers with kidney failure by means of the event of bioengineered kidney tissue with the flexibility to imagine important kidney capabilities.
“The transfer of this visionary expertise, developed by Jennifer Lewis, Ruji Morizane, and their colleagues, out into the world the place it can contribute to kidney restore and alternative therapies that sufferers so urgently want is a testomony to the Wyss Institute’s distinctive deal with advancing analysis and expertise improvement that end in optimistic close to time period impression. Now with Trestle, we stay up for seeing this expertise quickly advance to the clinic,” mentioned Wyss Founding Director Donald Ingber, MD, Ph.D., who can be the Judah Folkman Professor of Vascular Biology at HMS and Boston Kids’s Hospital, and Professor of Bioengineering on the Harvard John A. Paulson College of Engineering and Utilized Sciences.
