1. The document describes a study that isolated hepatic stem cells from human fetal liver tissue and characterized them by examining expression of liver-specific markers.
2. CD34-positive stem cells were isolated from fetal liver cells using magnetic sorting. These cells were characterized for viability, proliferation rate, and expression of alpha-fetoprotein, albumin, and cytokeratins 18 and 19.
3. The results demonstrate that the isolated CD34-positive cells expressed markers characteristic of hepatic stem cells, showing their potential for use in research and cell-based therapies for liver diseases.

16. Results and Discussion: 1. Fetal Dissection Ventral view of human fetal liver before perfusion. 1 , 2 , 3 , 4 – Liver lobes. 5 – Hepatic and portal vein. 6- Hepatic lymph nodes. 7- gall bladder.
17. 2. MACS Magnetic assorted cell sorter Pre-running column with saline Collection of CD34-ve cells Column is separated from magnetic field and Eluted with PBS. CD34+ve cells separated.
18. 3 . Viability Test ( Trypan Blue Staining ). Total number of cells = 2368cells/50 μ l Viable cells = 1600cells/50 μ l Dead cells = 768cells/50 μ l Total number of cells in area = 23.68X10 9 %viability = 67.56% Trypan blue staining of CD34+ve cells from human fetal liver cells.
