Die Geheimnisse des großen Weltgesetzes von einem berufenen Experten erklärt. Die Antwort auf die Fragen des Menschen nach dem Woher und Wohin!

The chicken is a useful model for research into the basic features of immunology because its immune system functions in a way similar to that of human beings and because the chicken embryo is easily accessed experimentally. This book is a collection of comprehen- sive articles updating chicken embryogenesis and immunology. It is now clear that it is possible to produce transgenic chickens by embryonic stem cell manipulation and transfer into the oocyte. Alternatively, the chick offers us the possibility of producing somatic chimeras by manipulating embryonic cells at the primitive streak or...

This book presents the current knowledge on the structure and function of the major families of cell adhesion molecules, the integrins, the selectins, the immunoglobulins superfamily and CD44, concentrating on their role in the immune system. Complex interactions between the members of these families mediate diverse adhesion functions, including leukocyte-leukocyte interactions, lymphocyte homing, inflammation, and lymphocyte-stromal cell interaction during homopoiesis. A great deal of emphasis is placed on the regulatory elements that control the expression and function of adhesion...
