Healthgen Biotech Wonderful memories at KSSCR International Symposium 2019

On September 26-28, 2019, the 3-days KSSCR International Symposium 2019 was successfully ended in Grand Hilton Seoul, South Korea.  

2019 ISSCR/KSSCR International Symposium is a joint meeting of the Korean Society for Stem Cell Research (KSSCR) and the International Society for Stem Cell Research (ISSCR), the largest and the most authoritative stem cell society in the world. More than 800 participants from Korea and abroad participated in this international symposium, and many wonderful moments are worth aftertaste.

Wuhan Healthgen Biotechnology Corp. (Healthgen Biotech) had a stand in the Symposium, showed the Recombinant Human Serum Albumin(OsrHSA) and Recombinant Human basic Fibroblast Growth Factor(OsrhbFGF), etc, which have been well-received by visitors.

Using the rice endosperm specific expression platform, Healthgen Biotech has expressed the animal component free recombinant proteins and growth factors. The products can help to keep good batch consistency and eliminate any risk of animal contaminants, which play an important role in in stem cell research, such as iPS, MSC.

OsrHSA, a recombinant human serum albumin derived from rice grains, which is animal component free, can avoid the prions or virus contaminants. The OsrHSA has very good batch consistency, which works as a kind of additive ingredient used in stem cell culture and can keep stem cell undifferentiation and viability. OsrHSA is determined to be equivalent to pHSA in terms of biochemical properties, physical structure, functions, biologic safety and immunogenicity.

The immunofluorescent staining of induced pluripotent stem cells(iPSCs) showed OsrHSA was effective in keeping undifferentiation and keeping viability of iPS cells.

OsrhbFGF, the Recombinant Human basic Fibroblast Growth Factor(OsrhbFGF) expressed in rice endosperm, which is animal component free, has very good batch consistency. The OsrhbFGF purity is higher than 95% and bioactivity is more than 1x10^6 IU/mg.

It has been demonstrated that OsrhbFGF has almost equal performance for feeder-free culture of iPS cells compared to control rbFGF(E.coli).

In the Mesenchymal Stem Cells(MSCs) culture, it showed that the proliferation rate and viability of MSC in the medium which was added in OsrhbFGF was similar to the medium (containing rbFGF derived from E. coli). The cell proliferation date showed that OsrhbFGF stimulating cell profiferation activity is equivalent to rbFGF(E.coli) for MSCs culture.

In the Symposium, Healthgen Biotech also exhibited other products,

Recombinant Human Epidermal Growth Factor, rhEGF
Recombinant Human Insulin-like Growth Factor-1 LR3, rhIGF-1 LR3

Recombinant Human Fibronectin, OsrhFN

Recombinant Human Lactoferrin, OsrhLF

These products have been widely used in stem cell culture and cell therapy.

In the stem cell culture, Healthgen Biotech products have following advantages:

• Non animal component, elimination or reduction of the potential risk of viral and other unknown factors in blood derived products;

• Excellent batch consistency, avoid the serum quality changes from different batches, improve the repeatability of cell culture and experiment results;

• Large-scale production can reduce the high cost.

• Well defined culture medium component

• Stable supply and no dependence on a process from precious blood source;

• Simplify the downstream bio-processing or biological research.
