BIOMIMESYS® Liver represents a new generation of mimetic HydroscaffoldS™ for 3D culture of hepatocyte-like cells. Available in a ready-to-use format, it enables the culture of hepatocytes and hepatocyte-like cells under physiological conditions that are representative of the microenvironment found in the liver. The highly porous nature of the Hydroscaffold™ allows the rapid uptake of nutrients, oxygen, etc. into the cells to create a reproducible study model for all downstream analyses used with 3D hepatocyte-like cell culture (metabolism, toxicity…).

PRODUCT
BIOMIMESYS® Liver represents a new generation of
mimetic HydroscaffoldS™ for 3D culture of
hepatocyte-like cells. Available in a ready-to-use
format, it enables the culture of hepatocytes and
hepatocyte-like cells under physiological conditions
that are representative of the microenvironment
found in the liver. The highly porous nature of the
Hydroscaffold™ allows the rapid uptake of
nutrients, oxygen, etc. into the cells to create a
reproducible study model for all downstream
analyses used with 3D hepatocyte-like cell culture
(metabolism, toxicity…).
Hyaluronic acid (HA) is a major component of the cells’ extracellular matrix (ECM), biofunctionalized with
liver ECM components (Collagens type I and IV, galactosamine and cell binding domain of Fibronectin),
BIOMIMESYS® Liver Hydroscaffold™ for 3D hepatocytes culture is thus an ideal study model because it is:

Representative of the hepatocytes’ microenvironment in terms of cell-cell interactions, matrix
composition and cell-matrix interactions
Highly porous to analyze easily the supernatant (for toxicity and metabolism studies)
Transparent for direct visualization of cells
HYALURONIC ACID (HA) + Collagen I & IV system, major component of the adipocyte extracellular
matrix (ECM), where it plays an IMPORTANT ROLE in connective tissue.
HA-based Hydroscaffolds™ are formed by HA-grafted RGDS and galactosamine + Collagen I & IV
system crosslinking HA with ADH to form reticulated chains.
High molecular weight HA.

o Rheology: Young’s modulus: E= 0.6 ± 0.04kPa
o Swelling ratio = 60 ± 5g/g ?
HEPATOCYTES: HIGHLY POLARIZED AND COMPLEX CELLS
The liver is composed of various cell types, 60% of parenchymal cells or hepatocytes and 40% non-
parenchymal cells (1).
Hepatocytes are highly polarized cells with apical domain representing about 10 to 15% of the cell surface.
This domain is composed of a canalicular network formed between adjacent hepatocytes connected by tight
junctions. These bile ducts are approximately 1µm in diameter and carry bile acid secreted by hepatocytes.
The hepatocytes are highly complex cells providing a variety of functions, the main ones are grouped in the
term “ADMET” (Absorption, Distribution, Metabolism, Excretion, Transport). Hepatocytes control
homeostasis and toxicity of molecules, as they absorb these molecules from blood to metabolize and
redistribute them to various organs. Hepatocytes are also involved in the processing or degradation of
molecules with therapeutic purposes that can generate potentially toxic secondary compounds.
Therefore, during the development phase, about 40% of new drug candidates are discarded due to toxicity
(2). Early detection of this toxicity will not only allow saving money and time but also ethics by limiting the
use of animals.

Liver: LIVER EXTRACELLULAR MICROENVIRONMENT
Like most cells, the hepatocyte microenvironment plays an important role in the maintenance of
differentiation, polarization and cellular functions. The extracellular matrix (ECM) is a complex mixture of
functional and structural proteins, glycoproteins and glycosaminoglycans (GAG) organized in a tissue-specific
three-dimensional structure. Hence, many studies have shown the relevance of using de-cellularized organs

for hepatocyte culture, recreating a microenvironment favorable to the survival and maintenance of cell
functions (3, 4).
The liver extracellular microenvironment notably contains collagen I, collagen IV and fibronectin which play
a key role in the structuring of the tissue and maintenance of hepatocyte functions (5).
To mimic this bioactive microenvironment, HCS Pharma has developed the world’s first biomimetic
Hydroscaffold™ made of HA, collagen type I and IV, galactosamine and RGDS motif of fibronectin dedicated
to the culture of hepatocytes: BIOMIMESYS® Liver.

decellularized human liver (B, ref 5) and collagen fiber in decellularized rat liver (D, ref 6).
Cell cultures in BIOMIMESYS®Liver were performed with the HepG2 cell line and cryopreserved human
primary hepatocytes.
Seeding was performed following the protocol described in the “first steps” document with the following
cell densities and volumes:
Primary Hepatocytes: 25 μl with 75,000 cells / gel
HepG2: 25 µl with 50 000 cells / gel

READY TO USE
BIOMIMESYS® is EASY to handle g & READY-TO-USE. Upon receiving the vacuum sealed 96-well plate, open
it (under a hood) and add the cells directly on top of the matrix. Changing the culture medium is easy as
well. To remove medium, simply draw the medium with a pipette between the matrix and the edge of the
well. To refresh the medium, place fresh medium onto the surface of the matrix.
