IntestiCult™-SF 类器官生长培养基 (人)是一套完整的培养基，用于从人的肠隐窝高效地构建肠类器官并对其进行长期的维持培养。IntestiCult™-SF 是无血清且非条件培养基的配方。

肠类器官为研究肠道上皮提供了一个便捷的体外器官型培养系统。分离的肠隐窝在 IntestiCult™-SF 中培养时能快速形成复杂类器官。该类器官包含一个由具有极性的肠上皮细胞层包围而成的功能性腔体结构，细胞层中包含已知的成年肠上皮细胞类型。成熟的肠类器官会形成突出的芽体，与体内组织的肠隐窝结构相似。IntestiCult™-SF 支持患者活检样本中肠上皮干细胞的增殖，以及新鲜组织或现有冻存样本来源的类器官的扩增。

肠类器官培养的应用包括研究肠道上皮的发育和功能、构建肠道疾病模型，以及在肠道模型中筛选分子的有效性和毒性。肠类器官培养还可用于研究成体干细胞特性及再生治疗方法，并可通过 IntestiCult™ 类器官分化培养基 (人)（产品号 #100-0214）实现进一步分化。

Figure 1. Organoids Grown in IntestiCult™-SF Have a Comparable Morphology to Organoids Grown in IntestiCult Organoid Growth Medium (Human)

Human intestinal organoids grown in IntestiCult™-SF and IntestiCult™ Organoid Growth Medium (Human) display similar morphological characteristics during organoid maintenance and expansion. Shown are organoids from small intestinal and colonic tissues, established and expanded in IntestiCult™-SF or IntestiCult™ OGMH. Organoids are imaged at passage 5 of culture for all images. Scale bars = 500 μm.

Figure 2. IntestiCult™-SF Provides More Efficient Expansion of Intestinal Organoids Compared to IntestiCult™ OGMH

Human intestinal organoids established from both (A) small intestinal and (B) colonic tissues display more efficient expansion during extended culture when grown in IntestiCult™-SF compared to those grown in IntestiCult™ OGMH. Shown is the cumulative expansion of organoids averaged across two separate donor lines in each medium. IntestiCult™-SF demonstrates more efficient expansion of both small intestinal and colonic organoids during extended culture.

Figure 3. Organoids Grown in IntestiCult™-SF Display Some Characteristics of the Mature Intestinal Epithelium

While organoids grown in IntestiCult™-SF display a primarily "immature" phenotype including expression of (A) intestinal stem cell marker OLFM4 and (B) proliferation marker ki67. (C, D) These organoids also display some characteristics of the mature epithelium such as the presence of goblet cells (C, Muc2), enterocytes (C, KRT20), and enteroendocrine cells (D, CHGA). Scale bars = 50 μm or 20 μm as indicated.

Figure 4. Organoids Grown in IntestiCult™-SF Display Similar Genetic Expression Profiles to Those Grown in IntestiCult™ OGMH

Analysis of intestinal organoids grown in IntestiCult™-SF by qPCR of (A) Lgr5, (B) Muc2, (C) Krt20, and (D) ChgA demonstrates similar genetic expression profiles to those grown in IntestiCult™ OGMH, as well as to colonic and small intestinal tissue (A-D; x and + respectively). All expression levels are shown relative to ACTB and TBP house-keeping genes (HKGs). (E) Further analysis of three separate donors grown in IntestiCult™-SF (circles) IntestiCult™ OGMH (triangles), and published medium (squares) by principle component analysis demonstrates that differences between cultures are primarily due to donor variability with samples forming distinct clusters separated by donor, rather than by medium.

Figure 5. IntestiCult™-SF Enables Efficient Expansion of Intestinal Organoids from Polyp Tissue

Intestinal organoids were established from both normal epithelial tissue, as well as from polyp tissue, and expanded for three passages in IntestiCult™-SF. Shown are cultures from two separate donors, imaged at the end of each passage immediately before passaging.

Figure 6. Organoids Grown in IntestiCult™-SF can be Further Differentiated using IntestiCult™ Organoid Differentiation Medium

Further differentiation of organoids in IntestiCult™-SF can be achieved by passaging organoid cultures in IntestiCult™ Organoid Differentiation Medium as organoid-derived monolayers (2D Monolayer Diff) or in 3D organoid culture (3D Organoid Diff). Upon differentiation, markers for enterocytes (KRT20, ApoB), goblet cells (Muc2), and enteroendocrine cells (ChgA) are upregulated compared to organoids grown in IntestiCult™-SF.
