Derivation of human embryonic stem cell line Genea023

Area of Science:

• Stem Cell Biology
• Reproductive Medicine
• Genomics

Background:

• Human embryonic stem cells (hESCs) are crucial for regenerative medicine and disease modeling.
• Characterization of novel hESC lines is essential for expanding research capabilities.

Purpose of the Study:

• To characterize and validate the Genea023 human embryonic stem cell line.
• To assess its genomic stability and pluripotent potential.

Main Methods:

• Derivation from ART blastocyst via ICM outgrowth on inactivated feeders.
• Karyotyping (46, XY), CGH, and STR analysis for genomic integrity.
• Pluripotency assessment via marker expression (Nanog, Oct4, Tra1-60, SSEA4), Pluritest, Alkaline Phosphatase activity, and teratoma formation.

Main Results:

• Genea023 demonstrated typical pluripotent cell morphology.
• Genomic analysis confirmed a 46, XY karyotype and male allele pattern.
• High expression of pluripotency markers (Oct4, SSEA4) and successful tri-lineage differentiation confirmed pluripotency.
• The cell line tested negative for Mycoplasma and contamination.

Conclusions:

• Genea023 is a well-characterized, male human embryonic stem cell line with stable genomic integrity.
• Its validated pluripotency and safety profile support its use in various research applications.
• This novel hESC line expands the available resources for stem cell research.
