VeloGene's Ready-to-Use Feeder Cells for Robust Stem Cell Culture​Eliminate the inconsistency and labor-intensive process of preparing your own feeder layers. Our pre-tested, mitomycin-C-treated or gamma-irradiated feeder cells provide a reliable foundation for your most sensitive cultures. They are designed to secrete necessary nutrients and create an optimal microenvironment, maximizing plating efficiency and supporting long-term stem cell growth while minimizing spontaneous differentiation.

Product Features

1

High Nourishing Capacity

VelogGene Biotech's culture system provides high - nourishing capacity for ESC/iPSC colonies. These colonies feature a distinct dome - shaped form, clear edges, bright & transparent cytoplasm, and tight cell - cell connections, indicating no spontaneous differentiation. When ES cells cultured on our feeder cells are tested, the mouse live - birth rate hits 30% - 70%, far surpassing the 1% - 5% in existing literature. This showcases the high - nourishing capacity of our system, ensuring top - notch ES cell growth support.
2

Pre-inactivated Treatment​

The feeder cells are pre-inactivated with Mitomycin C (Mito-C), allowing for immediate use upon thawing. This pre-treatment saves researchers at least two weeks of preparation time. The treated cells are fully inactivated and exhibit almost no proliferation, thereby providing a stable growth environment for embryonic stem cell culture.
3

Rich Selection of Resistance Markers

This feeder cell line contains a variety of single and combined resistance markers, including Neo, Puro, BSD, and Hygro, catering to diverse experimental requirements. This allows researchers to select the most suitable feeder cells based on their specific experimental needs, thereby enhancing experimental flexibility and success rates.
4

High Post-Thaw Viability

The post-thaw attachment rate of the cells exceeds 80%, with the cells exhibiting a healthy morphology characterized by a three-dimensional, elongated spindle shape. This high post-thaw viability and optimal cellular morphology ensure that the feeder cells can rapidly fulfill their supportive function for embryonic stem cell growth, providing a reliable foundation for embryonic stem cell culture.

Feeder Cell Preparation Process​

Have you ever wondered how these remarkable feeder cells come to play a pivotal role in your scientific research? The journey of creating these essential cells is a meticulous scientific odyssey.
It all begins with the careful extraction of embryonic tissue from pregnant mice precisely at 13.5 days post - coitum. Through a sequence of painstaking separation and purification procedures, we isolate Primary Mouse Embryonic Fibroblasts (MEF cells), marking the starting point as passage 0 (P0).
These nascent P0 MEF cells then embark on a growth journey, undergoing expansion through successive passages. To ensure they serve their intended function without uncontrolled growth, we treat the expanded cells with Mitomycin C. This treatment effectively reins in their proliferative capacity, transforming them into the highly - valued feeder cells.
Once the feeder cells are ready, they are cryopreserved and securely stored in liquid nitrogen tanks, safeguarded for long - term use. Quality is the cornerstone of this process. Throughout the entire preparation, we implement rigorous quality control measures. We closely examine cell morphology to ensure the cells maintain their proper structure, conduct viability tests to confirm their health and functionality, and carry out mycoplasma detection to keep contamination at bay.
For researchers in stem cell research, tissue engineering, or any field where feeder cells are integral, understanding this preparation process is not just academic; it's the key to unlocking the full potential of these cells in your experiments. Whether you're aiming to support stem cell growth, study cell - cell interactions, or develop new therapeutic strategies, these feeder cells, crafted with precision, are your reliable partners.
