Mouse Anti-CD44 Recombinant Antibody (clone BU52) (CAT#: DrMAB-991)

Figure 1 CD44-expressing mesenchymal cells are found throughout newly formed fibrotic lung tissue obtained from patients who died from the fibroproliferative disorder of acute alveolar fibrosis after lung injury.

Lung tissue obtained immediately after death was snap frozen and immunostained with anti–CD44 monoclonal antibody.

Figure 3 Identification of the 85-kD fibroblast CD44 isoform by immunoprecipitation with anti–CD44 monoclonal antibodies.

Undigested and chondroitinase-digested Hermes 3 immunoprecipitated proteins from acute lung injury fibroblasts. Undigested and chondroitinase-digested proteins immunoprecipitated with monoclonal antibodies that only recognize the unsaturated bonds of either 4- or 6-sulfated chondroitin sulfate residues that remain attached to the core protein after chondroitinase digestion.

Figure 4 Anti-CD44 antibody inhibits acute lung injury fibroblast invasion of a fibrin matrix.

Acute lung injury fibroblasts were allowed to attach and spread (4 h, 378C) on the surface of tissue culture wells. They were then overlayed with a fibrin gel and cultured in the presence of anti–CD44 monoclonal antibody in varying concentrations: 0.01 mg/ml, 1.0 mg/ml, 20 mg/ml, or an isotype IgG1 control monoclonal antibody.

Figure 5 Fibroblast migration on the provisional matrix proteins fibronectin, fibrinogen are blocked by anti-CD44 antibody.

Acute lung injury fibroblasts were preincubated for 30 min with varying concentrations of antiCD44 antibody. Fibroblast migration to the undersides of filters coated with fibronectin was assessed using modified Boyden chambers in the presence of anti–CD44 antibody or IgG1 isotypematched control antibody.
