Definitions
- the present invention relates to a device for measuring the migration ability of amoboid-movable cells consisting of a plate-shaped active substance depot, a membrane filter located thereon and at least one container arranged thereon and provided with a bottom opening, the bottom opening of the container abutting the membrane filter.
- Active substances are understood to be all substances which have a promoting or inhibiting effect on the migration of amoboid-mobile cells.
- the object of the invention is to improve this device known from the prior art for measuring the migratability of amoboid-movable cells in such a way that, on the one hand, the effectiveness of this device and its measuring accuracy are increased, and on the other hand, the measuring method is considerably simplified and its implementation is significantly be accelerated, which facilitates the implementation of measurement series.
- the area of the membrane filter is at least 1.6 times as large as the area of the bottom opening of the container.
- the active substance depot is connected to the membrane filter by gluing, individual gluing points being distributed over the surfaces to be glued, for example in a lattice-shaped grid, the total gluing surface being a maximum of 30% of the adjoining surfaces of the active substance depot and the membrane filter.
- the active substance depot, the membrane filter and the container are placed on a carrier plate made of a transparent or translucent material and the active substance depot and the membrane filter are made of a transparent material or a material which can be changed into a transparent state. This makes it possible to evaluate the migratability of the cells in a microscopic transmitted light method.
- the membrane filter is preferably designed as an at least approximately rectangular plate, on the underside of which a plurality of active substance depots are attached, in particular by adhesive, and on which a plurality of containers for the cells to be examined are arranged, each container being assigned its own active substance depot.
- the containers can be arranged in rows next to one another, the containers in a row being connected to one another by webs or the like to form units.
- the container can also be connected to the membrane filter by gluing.
- This adhesive is preferably designed so that it can be easily removed from the membrane filter after the migration process and without damaging it.
- the active substance depots, the membrane filter and the containers located above are preferably also placed on an elongate carrier plate made of a transparent or translucent material, and the active substance depots and the membrane filter are made of a transparent material or of a material that can be changed into a transparent state.
- FIGS. 2 and 2a show a second embodiment of a device according to the invention, which represents a measuring unit and which facilitates the implementation of large-scale measurement series, in a vertical section along the line AA 2a and in plan view.
- FIG. 1 shows a carrier plate 1 on which an active substance depot 2 is located.
- a membrane filter 3 which is connected to the active substance depot 2 by means of several adhesives 4.
- a tubular container 5 into which a liquid 6 is introduced, which contains cells 7, the migration ability of which is to be measured.
- the membrane filter 3 has an area which is at least 1.6 times the size of the bottom opening of the container 5.
- the membrane filter 3 exerts a suction effect on the liquid 6 with the cells 7 contained therein.
- liquid also gets into the active substance depot 2 arranged below the membrane filter 3, portions of the active substance being dissolved which subsequently diffuse into the membrane filter 3 and into the liquid located above it. This acts on the cells 7 in such a way that their immigration into the membrane filter 3 is influenced.
- the area of the membrane filter 3 is at least 1.6 times as large as the bottom opening of the container 5. a much stronger suction effect is exerted on the liquid 6 in the container 5 with the cells 7 contained therein than is the case when the membrane filter is approximately the same size as the bottom opening of the container 5. As a result, the cells 7 are brought into contact with the membrane filter 3 more quickly and can penetrate the membrane filter 3 more quickly, as a result of which the measuring time is shortened.
- the active substance depot 2 is closely connected to the membrane filter 3 by adhesive, the active substance is dissolved and diffused into the membrane filter 3 and further into the liquid 6 in the container 5 in a controlled and uniform manner, which is one of the prerequisites for the Represents reproducibility and standardizability of migration measurements.
- the totality of the adhesive surfaces 4 must not cover more than 30% of the surfaces lying against one another, since otherwise the diffusion of the liquid into the active substance depot 2 and also also the diffusion of the dissolved active substance from the active substance depot 2 into the membrane filter 3 would be severely restricted .
- the individual adhesive surfaces 4 can be arranged in a grid-like pattern.
- the cells that have migrated into the membrane filter 3 e.g. by coloring, made recognizable, after which their number, distribution and shape are determined by means of a microscopic evaluation method. If the components of the device are transparent or can be made transparent, a transmitted light method can be used for this.
- FIGS. 2 and 2a The basic structure and the basic function of such a device are explained with reference to FIG. In contrast, such a device is shown in FIGS. 2 and 2a, by means of which it is easier to carry out measurement series.
- this device several of the components shown in FIG. 1 are combined to form a measuring unit, which enables a simple, rapid and easily manageable migration measurement.
- This device consists of a rectangular support plate 1 1, which is preferably made of a transparent or translucent material.
- a mat-like membrane filter 13 which covers a plurality of active substance depots 12 spaced apart from one another.
- the active substance depots 12 are connected to the membrane filter 13 by means of several adhesives 14.
- the active substance deposits 12 and those portions of the membrane filter 13 which do not cover the active substance deposits 12 are also connected to the carrier plate 11 by adhesives.
- two rows of three containers 15 and 15a are located above the membrane filter 13, into which the liquid 16 with the cells 17 to be examined is introduced.
- the individual containers 15 and 15a of the two rows are connected to one another by means of webs 18 and 18a.
- the active substance depots 12 located under the three containers 15 are loaded with an active substance, whereas the active substance depots located below the containers 15a arranged in parallel do not contain any active substance because they serve to measure the unstimulated, spontaneous cell migration.
- the triple measurement carried out simultaneously in the application example serves to increase the measuring accuracy.
- the active substance depots 12 under the containers 15 and 15a are each loaded with different active substances, as a result of which their different effects on the migration of the cells to be examined can be compared.
- the cells immigrated into the membrane filter 13 are fixed and stained by pouring suitable substances into the containers 15 and 15a. After completion of the preparation, the containers 15 and 15a are detached from the membrane filter 13. The cells that have migrated into the membrane filter 13 are then accessible for microscopic examination.
- the containers 15 and 15a have an internal diameter of approximately 7 mm and a height of approximately 9 mm.
- the membrane filter 13 and the active substance depots 12 each have a thickness of 140 ⁇ m.
- the containers 15 and 15a and the carrier plate 11 can be made of plastic or glass. The decisive factor here is that they are indifferent to the media used and the cells to be examined.
