nanofibrillar basement membrane mimic made of recombinant functionalized spider silk in custom-made tissue culture inserts

In vitro models that can replicate tissue barriers have received increasing attention due to their applicability in testing novel therapeutics and facilitating the understanding of fundamental disease mechanisms1,2. To accurately recreate the native microenvironment, it is critical to recapitulate the function of the basement membrane (BM), a highly specialized extracellular matrix (ECM) complex. The BM exists in almost every tissue in the human body, where it provides support to endothelial and epithelial cells and separates them from underlying tissue2,3. Beyond providing physical support, the BM also regulates and maintains biochemical signals between the cells and surrounding tissue. These vital functions make it necessary to design scaffolds that resemble the structure, as well as the mechanical and functional characteristics of the native BM3.
One of the most common ways to mimic the BM in vitro today is through the use of commercially available tissue culture inserts (TC-inserts). These are essentially plastic cylinders with a permeable membrane that divides the chamber into apical and basolateral sides4,5. While easy to use, the membranes in commercial inserts are generally rigid, track-etched, and made from polymers such as poly(carbonate) (PC) and poly(ethylene terephthalate) (PET)3,4,6. They are flexible in terms of diameter, pore density, and size and can be coated to enhance cell adhesion but lack all other relevant features of the BM, such as comparable thickness6, interconnected porosity, fibrous architecture, and relevant elastic modulus3.
The standardization of TC inserts and their ease of use has inspired several groups, including ours, to replace the plastic membrane with a more in vivo-like counterpart (overviewed in Table 1). The materials used range from polymers such as Polydimethylsiloxane (PDMS)7, Poly(lactide-co-caprolactone) (PLCL)8, and polycaprolactone (PCL)4,9,10 to protein-based materials such as gelatin2,11,12, collagen5,13, and recombinant spider silk14,15,16,17. Membranes from these materials have been attached in various ways, both to commercially available inserts from which the membrane has been removed4,7,8,10,12,13,14,16,18,19,20,21, as well as to custom-designed inserts manufactured through 3D-printing1,11,15,17,20 or injection molding9,22. However, most of these still come far from resembling the native BM in terms of thickness, where the replicas range from hundreds11,18 down to a few micrometers5,10,14,21,22. Many of them also require complex formation and/or manual attachment methods1,7,13,14,18,19,21, making scaling and replication in other labs challenging.
Herein, we present a simple method to form and attach a silk membrane to inserts and show how to culture cells on either side of the membrane. The silk membranes are formed through self-assembly of the FN-4RepCT (FN-silk) protein at the liquid-air interface of a standing solution16,17. FN-silk is a recombinantly produced short version of Major Ampullulate Spidroin 1 from Euprosthenops australis, functionalized with an RGD motif derived from fibronectin23. It has been shown to assemble into fibrillar matrices that promote cell adhesion, growth, and migration15,16,17,23,24,25. The method for attachment of the membrane on the insert relies on spontaneous adhesion and has been found suitable for commercially available inserts from which the membrane has been removed16, as well as 3D-printed inserts from polylactic acid (PLA)17 and Dental LT15. This paper details how this method is used for inserts printed from Dental LT. After the FN-silk membranes have been attached to the inserts, they can, in essence, be treated like standard commercial tissue culture inserts. In short, we present a simple method to generate more relevant in vitro models of tissue barriers by replacing plastic membranes with a protein-based, FN-silk membrane.

Our research focuses on using recombinantly produced functionalized spider silk proteins to create extracellular matrix models to create more in vivo-like conditions for the cells. We're hoping that by creating a more realistic condition for the cells we're growing, they will grow into tissue-like construct just like they would inside the body, resulting in more realistic models. So the main advantage with using our FN-silk membranes instead of the commercially available plastic PET membranes is that the user gets a membrane that actually resembles the native basement membrane in terms of structure, thickness, biological composition, and elasticity.By using a membrane that comes closer to mimicking the native basement membrane, we're able to establish more realistic in-vitro tissue models. This can speed up drug discovery and further reduce the need for animal testing. We will continue to investigate how the FN-silk membrane can further improve static in-vitro tissue models, and we will also incorporate the membrane into microfluidic chips in order to expose the cells to flow.This way we can further involve in-vitro models towards more in vivo-like conditions.

Replicating tissue barriers&#160;is critical for generating relevant in vitro models for evaluating novel therapeutics. Today, this is commonly done using ...
