Bioprinting cell therapies to treat cartilage injuries


An innovation in
cellular technology

Cartilage injuries occur in two thirds of all joint trauma, with many leading to osteoarthritis that cannot be adequately prevented or treated using current complex surgery interventions.

To combat this, the Axcelda team have developed a suite of technologies to accurately repair the joint injury by rapidly isolating stem cells from a patient (AxceldaQik™), combining with a proprietary biomaterial scaffold (AxceldaInk™) and then printing new cartilage using a hand held device (AxceldaPen™) directly into the defect.

Our combination of stem cell technology, engineering and surgical innovation promises to simplify surgery through a one-off surgical procedure with the capacity to bank cells for future use (AxceldaLab™) if repeat surgery is required.

Granting surgeons greater control in theatre


Supported by 10+ years of laboratory and engineering research and development.


An innovative system that brings together the latest technology in biomedical engineering, biomaterial science and surgical techniques to create a dynamic technology offering.


A novel turn-key solution for the surgeon and patients for the repair of cartilage defects.



A lightweight, handheld ‘bioprinter’ allowing the surgeon to precisely pattern hydrogels and stem cells within a defect site, to surgically sculpt the articular surface, and to repair cartilage in the knee. AxceldaPen includes features to cure the scaffold material in situ using visible light, to achieve fixation and load-bearing capacity.


A proprietary biodegradable material based upon natural matrix proteins in human articular cartilage. AxceldaInk is formulated to carry the patient’s stem cells safely through the printing nozzle, and to form a temporary cartilage ‘scaffold’ after deposition. Once implanted, cells actively break down the scaffold and replace it with brand new cartilage tissue.


An innovative and streamlined technology that accelerates the retrieval of regenerative stem cells from the patient’s own fat, without using animal derived processing enzymes, and without leaving the surgical field. AxceldaQik enables immediate reimplantation in a single surgical procedure.


Off-site, proprietary technology to retrieve, expand, separate and store patient-derived stem cells in large numbers. AxceldaLab provides an economical solution for patients and hospitals to bank populations of their own regenerative stem cells for use in future surgery.


Combining research with medical expertise and entrepreneurship

Axcelda brings together surgeons, mechatronic engineers, material scientists, bioengineers, biologists and other talented people with expertise in design, manufacture, quality control, regulatory, patent and intellectual property protection and product commercialisation.
