Endothelial progenitor cells (EPCs) |
Anti-fibrotic and pro-regenerative properties |
Complicated isolation process, unclear clinical efficacy |
(24, 25) |
Hematopoietic stem cells |
Pluripotency
Potential to self-renew
|
Requires bone marrow aspiration
Linage derivation (such as derivation to macrophages)
|
(26, 27) |
Hepatoblasts (Fetal liver Stem Cells) |
1. these cells are bipotent, being able to give rise to both hepatocytes and bile duct cells |
Rarity of hepatoblasts 0.1% of fetal liver mass
Presence of oval cells in adult liver (make isolation an expansion difficult)
|
(28–30) |
Hepatocytes |
Key metabolic and synthetic cells of the liver
Suitable for replacing enzyme deficiency
Suitable for replacing metabolic disorders
|
Donor shortages
Limited engraftment and proliferation
Infection risk
|
(31, 32) |
Immune cells |
Relatively easy to isolate and culture |
Potential ability to induce inflammatory storms |
(33) |
Induced pluripotent stem cells (iPS) |
an unlimited source to produce hepatocytes-like cells In vitro
Lack of potential issues of allogenic rejection
|
Ethical concern
Malignancy potential
Low production efficiency
|
(34, 35) |
MSCs |

pluripotency
immunomodulatory and anti-inflammatory properties
Anti-fibrotic function
Extracellular signaling
Allograft potential
Diffreniatonal ability
|
Pro-tumor potential
