Intestinal Subepithelial Myofibroblasts Support the Growth of Intestinal Epithelial Stem Cells

The supportive ISEMF population was able to rescue crypts grown without exogenous Rspo1, a growth factor thought to be necessary for in vitro epithelial monoculture.

Among those cells in intimate contact with crypts lri vivoISEMFs may serve as natural feeder cells for in vitro intestinal epithelial culture. We never store sensitive information about our customers in cookies. Small intestinal crypts were isolated from adult eGFP mice ranging lel weeks old, using a previously described protocol [8].

Reverse transcriptase qPCR confirmed overexpression of Acta2 and vimentin relative to murine whole intestine, as well as negligible desmin expression Fig. After 28 days in vivohistologic assessment of the retrieved co-cultures showed evidence of viable enteroids, with a preserved immunophenotype Fig.

Cititi politica de protectie a datelor aici. Annual Review of Physiology These lri were co-cultured in intimate contact with crypts, using culture media either devoid of R-spondin or containing Rspo2.

R-spondin2 is a promising candidate responsible for signaling between ISEMFs and stem cells in vivoand this possibility warrants further investigation. Wnt signaling has been shown to be essential for ISC maintenance, and its removal results in terminal differentiation and ultimate loss of the intestinal epithelium [14].

Conclusion We conclude that co-culture of intestinal epithelial stem cells with ISEMFs yields larger enteroids with improved viability, even in the absence of exogenous growth factors.

In vivoRspo2 has lwi reported to enhance the growth of intestinal epithelial precursors and inhibiting differentiation llei.

We especially are grateful to I. In vitro cultures and in vivo explants were fixed and processed for paraffin embedding as previously described [8]. We hypothesized that ISEMFs provide necessary growth factors for the in vitro culture of intestinal epithelium derived from crypts and single ISCs and would further allow for their successful in vivo implantation.

The Journal of Leei Investigation Lgr5 is a co-receptor for the canonical Wnt pathway which is activated through the binding of R-spondin proteins [12].

Email address subscribed successfully. After ISEMFs attached and formed colonies, they were subsequently passaged and expanded using standard cell culture techniques.

Abstract Intestinal epithelial stem cells ISCs are lri focus of recent intense study. Implants containing only mono-cultured crypts without ISEMF consistently did not yield any epithelial cysts, thus confirming that ISEMFs are necessary to maintain the intestinal epithelium in vivo.

Previously described culture methods require exogenous Rspo1 for crypt or stem cell survival [15][23]. The American Journal of Physiology When treated with media lacking exogenous Rspo1, crypt monocultures did not form enteroids and died within two days of plating, highlighting the previously described necessity for Rspo1 [15].

Aliquots were microcentrifuged to yield crypts pellets for culture purposes. Intestinal epithelial stem cells ISCs are the focus of recent intense study.

Crypts formed budding enteroids in both conditions and had similar enteroid forming efficiencies Fig.

However, the requirement for a substantial amount of harvested tissue to generate 1145 modest quantities of neomucosa limits the clinical utility of this approach.

Cdx2 immunostaining confirmed the intestinal origin of the cysts Fig. Histology In vitro cultures and in vivo explants were fixed and processed for paraffin embedding as previously described [8].

Interestingly, Rspo2 has been found to be a more potent Wnt agonist than Rspo1 [26]which has traditionally been used in in vitro cultures [15].

The presence of mature epithelium was also confirmed by immunohistochemistry Fig. The close spatial relationship between ISCs and ISEMFs is likely a critical factor for in vivo survival in the absence of exogenous supplementation of growth factors.
