Microfluidic flow cell and system for analyzing or diagnosing biofilms and cell cultures, and the use thereof
Microfluidic flow cells for analyzing or diagnosing biofilms and cell cultures. The microfluidic flow cells comprise a support plate with a sample chamber formed therein, which is peripherally limited by chamber walls and a bottom, a cover plate which can be connected to the support plate in a fluid-tight manner, an inlet with an integrated inlet channel, which leads to the sample chamber via an opening, a drain with an integrated drain channel. Holding elements for fixing the support plate to a microscope stage or a holding device are attached to the front sides of the support plate. The invention further relates to systems and their use for analyzing and diagnosing biofilms and cell cultures using these microfluidic flow cells.
BIOCOMPATIBLE COMPOSITE MEMBRANE, METHOD FOR FABRICATING THE MEMBRANE, BIOREACTOR AND METHOD FOR INVESTIGATING CELLS ATTACHED TO THE BIOCOMPATIBLE COMPOSITE MEMBRANE
In various embodiments a biocompatible composite membrane for in vitro cell culturing comprising a first material, which is non-water soluble and a water soluble second material is provided, wherein the composite membrane comprises a porous scaffold and a filling layer, the scaffold comprising the first material and the filling layer comprising the second material. Further, a method for fabricating the membrane, a bioreactor for use of the membrane in cell-stretch experiments and a corresponding method for investigating cells attached to the biocompatible composite membrane are also provided.
CELL HOLDING AND TRANSPORTING DEVICE
Problems: A devise for retaining and transporting cells that is capable of holding cultured cells and moving the cells while holding them is provided.
Solutions: The device for retaining and transporting cells 100 has a base 101, a through hole 103, a cell scaffold 105, and an manipulating part 107. The cell scaffold 105 holds cells such as cardiac myocytes and nerve cells. When holding the cells in the cell scaffold 105, drop the suspension from the through hole 103 to the cell scaffold 105 exposing from the through hole 103 using a pipette etc. and culture. The manipulating part 107 is formed so as to project from the upper surface P101a of the base 101. Multiple manipulating part 107 is formed radially on the upper surface P101a of the base 101, centered on the through hole 103. By forming the manipulating part 107, the manipulating part 107 can be held by a holder such as tweezers, which enables easy operation of the device for retaining and transporting cells 100.
MECHANICAL TRANSFECTION DEVICES AND METHODS
A transfection device suitable for delivery of various macrostructures (e.g., mitochondria, bacteria, liposomes) is described and uses mechanical force to thereby induce active endocytosis in a target cell. Contemplated devices are able to achieve high throughput of transfected cells that remain viable and are capable of producing colonies.
