Comparative Studies on Eosinophil Chemotactic Factors during Leukocyte Migration under Agarose

, 1982
Several known eosinophil chemotactic factors are compared with regard to their biological behavior during in vitro migration under agarose: zymosan activated serum (Zas), containing the chemotactic fragment C5a, the lymphokine eosinophil stimulation ...

Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy

Advanced Healthcare Materials, EarlyView.
This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for

Human melanoma metastasis culture supernatant contains chemotactic factors for phagocytes

, 1990
Several findings point out that melanoma culture supernatants release soluble factors which modulate mononuclear cell chemotactic responsiveness. In this regard, either an enhancement or an impairment of chemotactic capacity has been found.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Denervated Schwann cells attract macrophages by secretion of leukemia inhibitory factor (LIF) and monocyte chemoattractant protein-1 in a process regulated by interleukin-6 and LIF

, 2002
Injury to peripheral nerves results in the infiltration of immune cells, which remove axonal- and myelin-derived material. Schwann cells could play a key role in this process by regulating macrophage infiltration.

Chemotactic Factor Inactivator in Normal Human Serum

, 1973
Normal human serum contains an inactivator of chemotactic factors for neutrophilic leukocytes. The chemotactic factor inactivator (CF-I) remains soluble when serum is fractionated with ammonium sulfate (at 45% saturation), directly and irreversibly ...
