In Echinoderm larvæ, for instance, which undergo rapid metamorphoses, the disappearing organs break down into albuminoid globules, which are devoured and digested by the mesamœboids, or phagocytes, as Metschnikoff terms them. The latter also ingest small foreign particles which may be forced into the segmentationcavity. In many cases the mesamœboids fuse to form a plasmodium or giant cell, in order to effect this more readily ; in some cases the mesamœboids merely collect round the foreign body in order to isolate it.

In the youngest stage yet observed, the free human mesamœboids do not have any hæmoglobin. We must assume that in man also the primitive mesamœboids multiply, and that a part of them retain the primitive habitus.

Precisely similar cells make their appearance in the interior of the fat bodies, and result from the division and subdivision of the original cells in which the fat is deposited (see Chapter VIII.), and I have long held that the centrolecithal cells are mesamœboid or parablast cells.

There is a view that both the blood cells and the endothelium of blood vessels arise from certain mesamœboid cells of entodermal origin, which are insinuated between the entoderm and mesoderm but are not in the strict sense constituents of the latter, and which collectively have been called the angioblast. While the mesamœboid cells are probably identical with the primitive lymphocytes, the idea that they constitute a set of specific rudiments of entodermal origin, from which both blood cells and endothelium arise, has not been generally accepted.

The cortical portion of the thymus has a hematopoietic function and works in conjunction with the posterior lobe on the mesenchymal and mesamœboid tissues of the mesoderma.
