<li><span style="font-family: arial,helvetica,sans-serif;">Before thawing HuES cells, ensure that the MEF plate you have already prepared is properly plated and in good condition. DO NOT try to use a less than desirable plate, or one that is older than three days. It is recommended to pre-label all conical tubes and wells being used.<br /><br /></span></li>
<li>Pre-warm HuES media to 37&deg;C. Aliquot HuES media into a sterile conical tube for each line. Remove HuES vial/s from -80 and immediately submerge the bottom half of the tube in a 37&deg;C water bath. It should take about 45-60 seconds before the cells are 80% thawed (small frozen portion left).<br /><br /></li>
<li>Quickly bring the tube to the laminar flow hood, spray down with 70% alcohol, and gently transfer cells to the of pre-warmed media. Spin the tube, remove media, and resuspend in an appropriate volume of fresh, pre-warmed HuES media.<br /><br /></li>
<li>Aspirate off the MEF media from as many wells as you will be thawing into. Quickly, aliquot pre-warmed HuES media back into each well of the plate, being careful not to disturb the attached MEFs. Set the plate aside in the hood. As with MEFs, best results are obtained if the drops are evenly distributed about the plate. Carefully return the plate to a 37&deg;C incubator overnight to allow the HuES cells to seed the MEFs. Change media ~48 hrs after thaw, replacing with fresh HuES media.</li>

<p class="jove_content">In this video, we show how our laboratory routinely establishes a HuES human embryonic stem cell culture from a frozen stock.  This process is amenable for general use with any mammalian cell if frozen in a DMSO solution.  Efficient thawing is essential for establishing a new culture of HuES cells from a frozen stock, and is important for experimental consistency.</p>

Human ES cells: Starting Culture from Frozen Cells

Here we demonstrate how our lab begins a HuES human embryonic stem cell line culture from a frozen stock.  First, a one to two day old ten cm plate of  approximately one (to two) million irradiated mouse embryonic fibroblast feeder cells is rinsed with HuES media to remove residual serum and cell debris, and then HuES media added and left to equilibrate in the cell culture incubator.  A frozen vial of cells from long term liquid nitrogen storage or a -80C freezer is sourced and quickly submerged in a 37C water bath for quick thawing.  Cells in freezing media are then removed from the vial and placed in a large volume of HuES media.  The large volume of HuES media facilitates removal of excess serum and DMSO, which can cause HuES human embryonic stem cells to differentiate.  Cells are gently spun out of suspension, and then re-suspended in a small volume of fresh HuES media that is then used to seed the MEF plate.  It is considered important to seed the MEF plate by gently adding the HuES cells in a drop wise fashion to evenly disperse them throughout the plate.  The newly established HuES culture plate is returned to the incubator for 48 hrs before media is replaced, then is fed every 24 hours thereafter.

Here we demonstrate how our lab freezes HuES human embryonic stem cell lines.

Freezing Human ES Cells

Since James Thomson et al developed a technique in 1998 to isolate and grow hES in culture, freezing cells for later use and thawing and expanding cells from a frozen stock have become important procedures performed in routine hES cell culture. Since hES cells are very sensitive to the stresses of freezing and thawing, special care must taken. Here we demonstrate the proper technique for rapidly thawing hES cells from liquid nitrogen stocks, plating them on mouse embryonic feeder cells, and...

Freezing and Thawing Human Embryonic Stem Cells

We present a protocol for efficient reprogramming of human somatic cells into human induced pluripotent stem cells (hiPSC) using retroviral vectors encoding Oct3/4, Sox2, Klf4 and c-myc (OSKM) and identification of correctly reprogrammed hiPSC by live staining with Tra-1-81 antibody.

We describe a protocol to isolate and culture human amnion epithelial cells (hAECs) using animal product-free reagents in accordance with current good manufacturing practices (cGMP) guidelines.

This protocol provides a simple and efficient way to propagate human pluripotent stem cells (hPSCs) using only conditioned media derived from the human placenta in a gelatin-coated dish without additional exogenous supplementation or hPSC-specific synthetic substrata.

The human skin acts as a first line of defense against the external environment. We present a method for isolating primary human keratinocytes from adult skin. These isolated keratinocytes are useful in numerous experimental setups, and are a highly suitable model for studying molecular mechanisms in cutaneous biology in vitro.

Generation and Culturing of Primary Human Keratinocytes from Adult Skin

A protocol is presented to prepare polyvinyl alcohol-co-itaconic acid hydrogels with varying stiffness, which were grafted with and without oligopeptides, to investigate the effect of the stiffness of biomaterials on the differentiation and proliferation of stem cells. The stiffness of the hydrogels was controlled by the crosslinking time.

This protocol enables the maintenance of quiescent human hematopoietic stem cells in vitro by mimicking the bone marrow microenvironment using abundant fatty acids, cholesterol, lower concentrations of cytokines, and hypoxia.

Xenogeneic (chemical or animal-derived) products introduced in the cell therapy preparation/manipulation steps are associated with an increased risk of immune reactivity and pathogenic transmission in host patients. Here, a complete xenogeneic-free method for the isolation and in vitro expansion of human adipose-derived stem cells is described.

The current protocol details steps for troubleshooting induced pluripotent stem cell (iPSC) derivation from patient samples’ peripheral blood mononuclear cells (PBMCs) that have been difficult to reprogram following the manufacturer’s instructions. This protocol is specific to frozen buffy coat samples but may also be applied to the reprogramming of purified PBMCs.
