HepatiCult™ Organoid Kit (Human) Enables Liver Organoid Initiation, Expansion, and Differentiation

Figure 1. HepatiCult™ Organoid Kit (Human) Enables Liver Organoid Initiation, Expansion, and Differentiation

Human liver organoids can be grown from normal human liver tissue-derived hepatic ducts using the HepatiCult™ Organoid Kit (Human). (A) Cultures are established in HepatiCult™ Organoid Initiation Medium (OIM; Human) or HepatiCult™ Organoid Growth Medium (OGM; Human) (see Table 1 below) and subsequently passaged in HepatiCult™ OGM for expansion. (B) After passaging 2-3 times in HepatiCult™ OGM, cultures can be switched to HepatiCult™ Organoid Differentiation Medium (ODM; Human) to differentiate organoids towards more mature hepatic cell types. Refer to the Product Manual (Document #10000008301) for full culturing protocols.

Table 1. Product Recommendations for Liver Organoid Initiation, Expansion, and Differentiation

The recommended configuration of the HepatiCult™ Organoid Kit (Human) may differ based on starting material and experimental goals. When establishing liver organoid cultures from human liver tissue, HepatiCult™ Organoid Initiation Medium (OIM; Human) is recommended for efficient organoid initiation (see Figure 2 below). The expansion of already established organoids (fresh in culture or cryopreserved) is supported by HepatiCult™ Organoid Growth Medium (OGM; Human). These organoids should be maintained for 2-3 passages before further differentiation using HepatiCult™ Organoid Differentiation Medium (ODM). Refer to the Product Manual (Document #10000008301) for full culturing protocols.

HepatiCult™ Organoid Kit (Human) Provides Efficient Organoid Initiation From Human Liver Tissue

Figure 2. HepatiCult™ Organoid Kit (Human) Provides Efficient Organoid Initiation From Human Liver Tissue

(A) Organoid cultures were initiated in HepatiCult™ OIM, and then (B) passaged into HepatiCult™ OGM. For serum-free culture conditions, organoid cultures were both, (C) initiated in and (D) passaged in HepatiCult™ OGM. Culture images shown are from (A, C) day 15 following initiation, and (B, D) on day 8 of the first passage. (E) Quantification of organoid initiation efficiency shows a significantly higher organoid yield in HepatiCult™ OIM per gram of human liver tissue (mean ± SD; n=14).

HepatiCult™ Organoid Initiation Medium (Human) Supports Robust Organoid Establishment

Figure 3. HepatiCult™ Organoid Initiation Medium (Human) Supports Robust Organoid Establishment Across Multiple Liver Tissue Donor Samples

Organoids initiated from 4 donor tissue samples (A-D) exhibit morphological heterogeneity 15 days after initiation. All initiated cultures were subsequently expanded in HepatiCult™ OGM using a 1:1 passaging ratio (E-H), yielding healthy organoids at the end of the first passage.

Expansion of Organoid Cultures in HepatiCult™ Organoid Growth Medium

Figure 4. Expansion of Organoid Cultures in HepatiCult™ Organoid Growth Medium

Hepatic organoids show efficient growth in HepatiCult™ OGM across multiple donors and passages with potential for indefinite culture. Organoids initiated using the serum-free workflow exhibited comparable growth rates when expanded in HepatiCult™ OGM (open markers).

Proliferating Hepatic Organoids Display Characteristics of Hepatic Progenitors

Figure 5. Proliferating Hepatic Organoids Display Characteristics of Hepatic Progenitors

Human liver organoids grown in HepatiCult™ OGM display characteristics of proliferating hepatic progenitors observed through immunocytochemistry staining of (A) KI67, (B) HNF4A and (C) SOX9. Proliferating hepatic organoids also display characteristics of the hepatic epithelium including expression of (A) EPCAM. (B, C) Nuclei are counterstained with DAPI.

Proliferating Hepatic Organoids Maintain Genetic Expression Across Multiple Passages

Figure 6. Proliferating Hepatic Organoids Maintain Genetic Expression Across Multiple Passages

Liver organoids maintained in HepatiCult™ OGM express stem cell markers (A) LGR5 and (B) AXIN2, ductal markers (C) SOX9 and (D) KRT19, as well as hepatic marker (E) HNF4a and (F) Albumin (ALB) across multiple passages, with minimal albumin expression observed during culture in HepatiCult™ OGM. Expression levels were measured by qPCR and normalized to TBP and UBC housekeeping genes to quantify relative expression levels. (mean ± SD; n = 2-5 organoid lines), * p < 0.05.

Organoid Differentiation Induces Changes in Organoid Morphology

Figure 7. Organoid Differentiation Induces Changes in Organoid Morphology

Organoids exhibit a compact and dense morphology, often comprising thickened epithelia, upon switching cultures to HepatiCult™ Organoid Differentiation Medium (ODM). Shown are images of the same culture well over the course of the differentiation, including (A) day two of culture in HepatiCult™ OGM, (B) day five of culture, immediately after switching organoid cultures from HepatiCult™ OGM to HepatiCult™ ODM, (C) day seven of culture (two days after switching to ODM), (D) day ten of culture (five days after switching to ODM), and (E) day 15 of culture (ten days after switching to ODM). (F) Magnification of the rectangular section highlighted in (E).

Differentiation of Hepatic Organoids in HepatiCult™ ODM Induces Changes in Gene Expression Consistent with Hepatic Maturation As Analysed by RNA Sequencing

Figure 8. Differentiation of Hepatic Organoids in HepatiCult™ ODM Induces Changes in Gene Expression Consistent with Hepatic Maturation As Analysed by RNA Sequencing

Organoids expanded in HepatiCult™ OGM express markers associated with proliferative hepatic progenitor and ductal cells. Upon differentiation in HepatiCult™ ODM, organoids shift towards a more mature state, with increased expression levels of genes associated with key hepatic functions. This includes serum protein synthesis (ALB, SERPINA1), phase 1 and 2 drug metabolism (CYP2C9, CYP3A4, UGT1A1, GSTA1), glucose metabolism (SLC2A2, G6PC), bile acid synthesis (CYP27A1, BAAT), and urea synthesis (OTC). Genes associated with lipid and cholesterol metabolism are expressed at similar levels in both OGM and ODM organoids. Columns represent 3 biological replicates analyzed by bulk RNA-seq at passages 7 - 9 on day 5 in HepatiCult™ OGM and day 15 in HepatiCult™ ODM. The housekeeping gene, TBP, is included as a reference.

Differentiated Hepatic Organoids Demonstrate Functionality of Mature Hepatocytes

Figure 9. Differentiated Hepatic Organoids Demonstrate Functionality of Mature Hepatocytes

Upon differentiation in HepatiCult™ ODM, liver organoids were assayed for (A) albumin secretion, (B) CYP3A4 activity, (C) total bile acid production, and (D) urea production. Hepatic functionalities were compared to HepG2 cells and primary human hepatocytes (PHH), which were cultured in supplier-recommended media. Albumin secretion was detected using an ELISA kit (Abcam), total bile acid and urea production were analysed using colorimetric kits (Abcam), and CYP43A4 activity, referring to baseline activity without induction, was determined using the Luciferin-IPA kit (Promega). (mean ± SD; n = 3 organoid lines across 2 experiments, n = 2-3 technical replicates of HepG2 in 1 experiment, and n = 3 cryopreserved PHH donor samples in 1 experiment), * p < 0.05; ** p < 0.01.

Graphs demonstrating that CYP3A4 Activity Can Be Modulated in Differentiated Hepatic Organoids Upon Drug Treatment

Figure 10. CYP3A4 Activity Can Be Modulated in Differentiated Hepatic Organoids

Organoid cultures in HepatiCult™ ODM from three different donors were assessed for CYP3A4 (A) activity through LC-MS/MS and (B) gene expression through qPC R, demonstrating a time-dependent increase for both measurements. Gene expression levels were normalized to housekeeping genes, TBP and UBC, and ‘Day 0’ expression. To evaluate if CYP3A4 activity could be modulated, two differentiated hepatic organoid lines were treated with (C) calcitriol or (D) ketoconazole. CYP3A4 activity was assessed on day 15 of differentiation, 24 (open markers), or 48 hours post-treatment using the P450-Glo™ CYP3A4 assay (Luciferin-IPA) (Promega). Both differentiated hepatic organoid lines demonstrated a significant increase in CYP3A4 activity with increasing concentrations of calcitriol and a significant decrease in CYP3A4 activity with increasing concentrations of ketoconazole (n = 2 organoid lines, mean values from 2 experiments). Error bars = SD. One-way ANOVA with Dunnett's multiple comparisons test was used for statistical testing (**P ≤ 0.01, ****P ≤ 0.0001, ns = not significant).

IC50 Curves Demonstrating that High Drug Concentrations Disrupt Albumin Secretion in Differentiated Hepatic Organoids Consistent with Changes in Cell Viability

Figure 11. High Drug Concentrations Disrupt Albumin Secretion in Differentiated Hepatic Organoids

Organoids from two different donors were differentiated in HepatiCult™ ODM and treated with (A) troglitazone, (B) ketoconazole, (C) rifampicin, or (D) acetaminophen on day 7 of differentiation when the last media refresh was performed. Spent media was collected three days later on day 10, and accumulated albumin was measured using the MSD R-PLEX Human Albumin Assay. Organoids were also collected on day 10 and lysed for (E) viability assessments using the CellTiter-Glo® 3D Cell Viability Assay (Promega). Both differentiated hepatic organoid lines demonstrated a significant drop in secreted albumin upon treatment with high drug concentrations, corresponding with a decrease in cell viability (mean values from 2 experiments). Error bars = SD. One-way ANOVA with Tukey multiple comparisons test used for statistical testing (single asterisk or hash indicate P < 0.05, double asterisk or hash indicate P ≤ 0.01, triple asterisk or hash indicate P ≤ 0.001, quadruple asterisk indicate P ≤ 0.0001).

IC50 plots (drug dose-response viability curves) of primary hepatic organoids in comparison to HepG2 and PHH

Figure 12. Primary Hepatic Organoids Are Sensitive to Drug-Induced Hepatotoxicity in a Dose-Dependent Manner

Proliferating and differentiated hepatic organoids were treated with (A) troglitazone, (B) ketoconazole, (C) rifampicin, (D) acetaminophen, or 1% DMSO vehicle control for 3 days, with full-medium changes containing fresh compounds every 24 hours. Cell viability was assessed 24 hours after the last compound addition using the CellTiter-Glo® 3D Cell Viability Assay (Promega), and IC50 values were determined. These drug dose-response viability curves were compared to similarly treated HepG2 cells and primary human hepatocytes (PHH) cultured in 2D. Error bars = SD.
