Cell therapy is a relatively new discipline within the medical sciences. It uses intact cells, either human or microbial, to provide various benefits to the patient.
Cell therapies and regenerative medicine are two distinct, but overlapping, innovative disciplines in medicine. Not all regenerative medicine techniques involve the use of intact cells and not all cell therapies are regenerative in nature.
|Uses intact, living, whole cells|
|Cells can actively migrate to where needed|
|Cells can continuously produce compounds|
|Can control cells’ activity,|
replication and death
|Uses specific compound(s)|
|Compounds rely on body’s circulatory system|
|Dose needs to be controlled by intake|
|Little control over duration of activity —|
Reliant on body’s elimination system
These factors place them in a unique position to meet a range of critical unmet needs that more traditional pharmaceutical methods cannot. Such techniques have already showed promise for the treatment of cancers, infections, autoimmune and metabolic diseases, as well as tissue repair and regeneration¹.
The liver’s unparalleled regenerative ability makes it an excellent candidate for new potential regenerative medicine-based cell therapies. Promethera® Biosciences have already shown that mature hepatocyte transplantation can successfully improve liver function².
Mature hepatocytes, however, are difficult to produce and their cryo-preservation can be problematic. Therefore, Promethera® Biosciences is currently focused on developing an off-the-shelf technology with greater ease of manufacturing. Adult-derived liver progenitor cells cultured in vitro and then engrafted into livers have shown very promising results. These also have the potential to be used for pharmacotoxicology screening of new drugs and optimization of new compounds³.
Now that these products are involved in clinical trials for various liver diseases, Promethera® Biosciences has positioned itself as a global leader in cell therapy and regenerative medicine for the treatment of inborn and acquired liver diseases that have no effective therapeutic cure.
