Cell topology surface pattern base stiffness

Cell substrate stiffness regulation micro patterns and coupled perfusion and pressure stimulation culture

Features:

Control the 3D structure and mechanics of cells

Cells are cultured in a flat or microstructured soft 3D environment to mimic in vivo conditions.

The stiffness of the substrate can be selected from very soft (1 kPa) to very hard (200 kPa)

Provide various substrate morphologies (flat, circular holes, square holes, grooves, etc.)

The substrate based on gel is ready for your cell culture experiment

Due to the fact that cells are directly seeded on top of features (which makes it easy to restrict non migrating cells), it is easy to use and user-friendly

Pre coated ECM matrix (such as fibronectin)

Suitable for any cell culture substrate (cover glass, culture dish, porous plate)

The optical transparency of gel makes these substrates compatible with high-resolution optical microscope systems

Background:

Cells like softnessFlexcell®Founder and CEO Dr. Albert Banes said, "Over the years, cell culture has undergone changes, but the two popular innovations are the ability to grow and stretch cells on flexible growth surfaces and control substrate rigidity. Flexcell's new CellSoft ™ Cultivating the product further drives these innovations, and we know that researchers will love this product

“Cells like soft!” says Flexcell® Founder and President, Dr. Albert Banes, Ph.D. “Cell culture has met with change over the years, but two of the hottest innovations have been the ability to grow and stretch cells on flexible growth surfaces and to control the rigidity of the substrate. Our new CellSoft™ culture ware advances those innovations even further, and we know researchers will appreciate this product.”

Flexcell, a company based in the United States, commercialized the growth surface of elastomers in 1988 and provided a method device for controllably stretching cells based on the mechanics of heart, blood vessels, lungs, or other mechanically active tissues. Compared to glass or polystyrene culture plates, these elastomers have a "soft" and stretchable surface. With CellSoft ™， Flexcell ® Can create a softer matrix to matchOrganize niche (stem cell microenvironment)To better meet the needs of biological laboratories that wish to grow cells on natural rigid substrates based on their material properties.

Notes:The cradle like environment surrounding stem cells protects them, and this environment is calledniche.nicheNot only does it provide nutrients for stem cells, but it also guides their actions and determines the direction of their differentiation.

Flexcell® wasfirst to commercializeelastomer growth surfaces in 1988 and toprovide the meansto controllably stretch cells according to the mechanics of the heart, blood vessels, lungs, or other mechanically active tissues. These elastomer surfaces are“soft” and stretchable compared to glass or polystyrene culture plates. With CellSoft™, Flexcell® has created even softer substrates to match the material properties of tissue niches and better meet the needs of biological laboratories wanting to grow their cells on native stiffness substrates.

Flexcell®It is recommended that users cultivate their reserve cells on a given rigid substrate matrix coating and conduct experiments on the same type of surface. In this way, cells will not experience the "matrix shock" of transferring from one hardness and matrix coating to another hardness.

CellSoft™ Has various stiffness and plate formats (disc and porous plate). It can covalently bond with collagen I or other matrices, and has been pre sterilized and ready for use. CellSoft ™ A 100mm circular culture dish is ideal for passaging cells and other flat forms, including a flexible bottom Bioflex ® Flat plate for conducting static or dynamic tensile experiments.

CellSoftThere are many different types of culture plates, such as different hardness (elastic modulus range 1-80kPa), chamber slides (circular porous plates) that can be used for microscopic observation, covalently coated with Collagen I or other proteins, which can perform static or dynamic tensile stress stimulation on cells.
