The Essential 8™ Adaptation Kit includes Essential 8™ Medium and recombinant human Laminin 521 (rhLaminin-521) for optimal survival during transition from feeder-dependent to feeder-free culture. rhLaminin-521 has been proven to promote cellular survival under stressful conditions in the absence of small molecule inhibitors. In addition, rhLaminin-521 has been shown to support PSC growth for >20 passages without any signs of karyotypic abnormalities and to maintain the ability of PSCs to differentiate into all three germ line lineages. rhLaminin-521 can also be purchased separately.

The Essential 8 Adaptation Kit is:
• Robust–transition cells between feeder-dependent and feeder-free culture systems with minimal effort
• Physiologically relevant–expand cells with minimal differentiation
• Scalable–passage stem cell lines as single cells with no impact to genetic stability

Trouble-free transition
When used with Essential 8 Medium, rhLaminin-521 provides a robust culture matrix that supports pluripotent stem cell adherence and expansion during the transition from feeder-dependent culture systems.

Confident expansion
rhLaminin-521 is expressed in blastocysts and therefore provides an environment mimicking the human stem cell niche.

Easy scale-up
rhLaminin-521 promotes stable pluripotent stem cell maintenance as single cells in the absence of ROCK inhibitors.

For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

Can PSCs transitioned over into Essential 8 Medium on recombinant human laminin-521 (rhLaminin-521) from feeder-dependent cultures, then be transferred onto vitronectin (VTN-N)?

Yes. Following 2 passages on the rhLaminin-521 matrix, Versene or EDTA passaging should be used to subculture PSCs.

What are the main differences to be taken into consideration when culturing cells in Gibco Essential 8 Medium on Gibco Vitronectin (VTN-N) compared to other feeder-free systems?

Here are three major differences to be taken into consideration when culturing cells in Gibco Essential 8 Medium on Gibco Vitronectin (VTN-N) compared to other feeder-free systems:
- Cells should be typically passaged ~24 hours sooner than they would be with other feeder-free media.
- Passaging should take place when cells are at ~85% confluency. If cells are passaged when they are more than 85% confluent, the health of the cells and final cell yield may be compromised.
- Cells must be passaged in EDTA. Collagenase and dispase are not recommended.

Can pluripotent stem cells (PSCs) previously cultured in other media and on other substrates be cultured in Gibco Essential 8 Medium and on Gibco Vitronectin?

Cells cultured in other feeder-free media systems, such as mTeSR Medium with Matrigel Basement Membrane Matrix, or StemPro hESC SFM with Geltrex Matrix, can be successfully cultured in Gibco Essential 8 Medium and VTN-N. In addition, PSCs grown on feeders with KnockOut SR have also been shown to be successfully cultured in Gibco Essential 8 Medium on VTN-N. However, when changing media systems, cells must be passaged either manually, or with EDTA prior to culturing in Gibco Essential 8 Medium on VTN-N.

Can I use enzymes such as dispase and collagenase for passaging cells cultured in Gibco Essential 8 Medium and on VTN-N?

Enzymes such as dispase and collagenase do not work well with cells cultured in Gibco Essential 8 Medium on VTN-N. Use of these enzymes for passaging cells results in compromised viability and attachment.

Can pluripotent stem cells (PSCs) cryopreserved in a different culture condition be thawed and subsequently cultured in Gibco Essential 8 Medium and on vitronectin (VTN-N)?

Yes. PSCs cryopreserved from cultures of mTeSR Medium and BD Matrigel Basement Membrane Matrix may be thawed into Gibco Essential 8 Medium and plated on VTN-N. Certain lines may benefit from thawing into the medium and substrate they were growing in at the time of cryopreservation. Then at the next passage, use EDTA to passage the cells into Gibco Essential 8 Medium and VTN-N.
