Research & therapeutic potential of organoids includes: 99 99 99 99 99 99 Organogenesis Models Drug Testing Tumor, Disease and Infection Models Toxicity Screening Personalised Medicine Regenerative Medicine / Organ Replacement Preclinical models are falling short in predicting biological responses because plastic is not a natural component and mouse models are not representative of the human body. These models fail to recreate the complexity and the specificity of living tissues. To recreate In vivo structure and function the following factors are necessary to consider: In vivo structure and function: Factors to consider Organoid Culture Recreates In Vivo Structure and Function Tissue Resident Cells (Types, Quantities, Organization) Organoid Progenitor Cells (Differentiate into tissue-specific cells) Extracellular Matrix (Composition, Organization, Compliance) Extracellular Matrix (Basement Membrane Extract (BME)) Soluble Factors (Growth Factors, Cytokines) Soluble Factors (Wnt, Noggin, EGF, R-Spondin-1, TissueSpecific Factors) www.amsbio.com | [email protected] Page | 3 Organoid Models Organ Brain Retina Salivary Glands Esophagus Lungs Breast Heart Liver Kidneys Pancreas Stomach Small Intestine Colon Prostate Page| 4 Images and Results Citations and Protocols (pg 23) Pg 18, 19 3 Pg 19 Pg 13, 14 Pg 5, 15 Pg 16, 17 Pg 20, 21 Organoid Culture Handbook 1, 4, 10 1 7 2, 5, 7, 8 3, 6, 7 Featured Products for Organoid Culture Organoid Progenitor Cells Mouse Small Intestine Organoid Progenitor Cells Organoid 3D cultures represent the next generation of tissue culture models. These cultures are extracted directly from living tissues similar to primary cultures; however they are never subjected to an artificial, tissue culturetreated plastic environment. Instead, stem cell populations are maintained using a feeder-layer-free extracellular matrix environment under non-differentiating conditions. When subjected to differentiating conditions, these organoids exhibit expression of tissue-specific genes and differentiation of stem cells into tissue-specific architecture. The Cultrex® Organoid Progenitor Cells are derived from normal, healthy mouse small intestine tissue and are continuously cultured using Basement Membrane Extracts, designed and qualified specifically to promote robust organoid cultures (BME 2 and RGF BME R1). These organoid progenitor cells can be expanded and may be induced to express tissue-specific markers under differentiating conditions. A B Differentiation of Mouse Small Intestine Organoids Cultured on RGF BME R1. During expansion, Mouse Small Intestine Organoids grow as spherical structures (A), but under differentiating conditions, crypt-like structures bud from the organoid (B), mimicking intestinal epithelium. Nuclei were stained using DAPI (blue), and E-cadherin was visualized via immunofluorescence (green).

It is difficult to know which matrix formulation is best suited for any specific organoids, cell type, or application. However in competitive beta tests, BME 2 consistently outperforms competitor products. Each BME lot is qualified on Human Small Intestine Organoids. The Growth Factor Reduced format (BME 2 RGF “organoid matrix”) has been shown to work well for growing organoids, especially using techniques based on the LGR5 stem cell marker / Wnt signalling system, pioneered by Hans Clevers and co-workers. • • • • Each lot is validated for use in organoid culture Used extensively for organoid culture Reduced lot to lot variability Easy to use Recently we have developed an additional formulation of Cultrex® BME known as Cultrex® BME R1. This matrix provides a proprietary formulation that has higher tensile strength when compared to our other products Cultrex® BME, Cultrex® BME 2 and Cultrex® BME 3. It has a higher concentration of entactin, one of the BME components that connects laminins and collagens reinforcing the hydrogel structure. Cultrex® BME R1 has been specifically designed to culture tissue organoids. Page| 6 Organoid Culture Handbook Collagen I Type I collagen is the major structural component of extracellular matrices found in connective tissue and internal organs, but is most prevalent in dermis, tendons, and bone. It promotes cell attachment, proliferation, differentiation, migration, and tissue morphogenesis. Cultrex® Rat Collagen I, Lower Viscosity is diluted to a lower concentration (3 mg/ml); therefore it is less viscous and easier to handle. Name Cultrex® Rat Collagen I, Lower Viscosity Cultrex® 3-D Collagen I (From Rat Tail Tendons) Catalog Number Pack size 3443-003-01 3443-100-01 1 ml @ 3 mg/ml 35 ml @ 3 mg/ml 3447-020-01 20 ml at 5mg/ml Our 5 mg/ml rat collagen I (eg cat# 3447-020-01) is not pepsin treated, so it has intact telopeptides and is highly viscous. It is provided in acetic acid and requires pH neutralization prior to use. Do not to attempt to pipet this material using a graduated 1 ml pipette or narrow bore tip. Rather, we recommend using blue pipette tips (2001000uL capacity) that are clipped with sterile scissors to create a wide bore. Also, please consult the provided product data sheet for pH neutralization instructions. We also offer 3 mg/ml Cultrex® Rat Collagen I, Lower Viscosity (cat#s 3443-003-01 & 3443-100-01). Our 3D Collagen has been tested extensively for the ability to promote growth and differentiation of cell types, visualized by morphology in three dimensions in vitro (however, addition of laminin may be required as shown, for MCF-10A cells, in the product data sheet). Reagents R-spondin (RSPO1) Expressing Cell Line Roof plate-specific Spondin-1 (R-Spondin 1 or RSPO1), also known as CRISTIN3, is a 27 kDa secreted activator protein that belongs to the R-Spondin family. R-Spondins positively regulate Wnt/beta-catenin signaling, most likely by acting as a ligand for LGR4-6 receptors and an inhibitor for ZNRF3. R-Spondin-1 induces proliferation of intestinal crypt epithelial cells, increases intestinal epithelial healing, and supports intestinal epithelial stem cell renewal. The 293T cell line is stably transfected to express murine Rspo1 with an N-terminal HA epitope tag and fused to a C-terminal murine IgG2a Fc fragment. This cell line is used to produce either purified Rspo1 or Rspo1 conditioned media. The murine Rspo1 protein has been used extensively in organoid culture to maintain Lgr5+ stem cells, and the FC and HA tags make it easy to purify or characterize. Production of R-Spondin1 for organoid culture. The 293T cell line is stably transfected to express murine Rspo1 with an N-terminal HA epitope tag and fused to a C-terminal murine IgG2a Fc fragment. A) The HA-R-Spondin1Fc 293T cell line is cultured with zeocin to select for stably transfected cells. B) Production of HA-R-Spondin1-Fc is characterized using Western Blot for R-Spondin1 protein (arrow). C) HA-R-Spondin1-Fc induces activation of Wnt/ß-catenin response when evaluated using the Top-Flash Luciferase assay. www.amsbio.com | [email protected] Page | 7 BENEFITS •Cell line expresses recombinant mouse RSPO1 protein •Positively regulates Wnt/beta-catenin signaling •Essential medium component for most organoid culture models •Purified protein and conditioned medium from our cell line has been used for culturing both human and mouse organoids. Name Cultrex® R-spondin1 (RSPO1) Cells Catalog Number 3710-001-01 size 1 vial (0.5 ml), 1x106 cells Proteins and Antibodies The Wnt family of secreted glycoproteins is involved in several important cell functions such as cell proliferation, migration, polarity, survival, self renwal and cell fate. Among the most studied is a canonical Wnt signaling pathway that regulates quantity of transcriptional co-activator β-catenin and in turn β-catenin then regulates expression of the key developmental genes. In adition Wnt signals play an important role in the ability of organoids to expand. In particular Wnt3a and RSPO1 (which acts as an Lgr receptor agonist) are two important factors used for organoid expansion. AMSBIO offers a range of RSPO1 and Wnt3a recombinant human and mouse proteins. These human recombinant proteins are purified from HEK293 cells while the mouse proteins are expressed in CHO cells. Both are suitable for various cell assays and treatments.

However, the adaptation of these models for studying biochemical processes has been impeded by the challenge of separating intact organoids from extracellular proteins comprising the hydrogel. Commonly, proteases are employed to degrade these extracellular proteins, however, proteases also degrade proteins on the cell surface and protease activity may carry over into subsequent cultures or lysate preparations. Trevigen’s Cultrex® Organoid Harvesting Solution provides a ready-to-use, non-enzymatic method for depolymerizing extracellular matrix proteins to allow for harvesting of intact organoids for passaging, cryopreservation, or biochemical analysis. PROTOCOL BENEFITS • Ready-to-use • Non-enzymatic chelating solution • Depolymerizes basement membrane matrix for harvesting organoids from culture. • Gentle for cells: preserves original morphology APPLICATIONS • Organoid passaging • Sample preparation (PCR, Western Blot, and Immunohistochemistry) RESULTS • See example results on page 22.
