Electrospun nanofibres are an excellent cell culture substrate, enabling the fast and non-disruptive harvest and transfer of adherent cells for microscopical and biochemical analyses. Metabolic activity and cellular structures are maintained during the only half a minute-long harvest and transfer process. We show here that such samples can be optimally processed by means of cryofixation combined either with freeze-substitution, sample rehydration and cryosection-immunolabelling or with freeze-fracture replica-immunolabelling. Moreover, electrospun fibre substrates are equally suitable for complementary approaches, such as biochemistry, fluorescence microscopy and cytochemistry.
