Figure 4

CNV membranes with PDT-/TTT- and non- pretreatment. PDT pretreated. a) PDT pretreated membrane which mostly consists of a fibrovascular. tissue architecture. No immunoreactivity (negative control) without primary antibody (Anti Hsp70, magnification 20 x). The surrounding pink staining reaction is an artefact (arrow). b) PDT pretreated membrane with immunoreactivity to the anti-Hsp70 primary antibody (pink stained tissue). TTT pretreated. c) TTT pretreated membrane which mostly consists of a fibrovascular tissue architecture. No immunoreactivity (negative control) without primary antibody (Anti Hsp70, magnification 20×). The surrounding pink staining reaction is an artefact (arrow). d) TTT pretreated membrane with immunoreactivity to anti Hsp70 (pink stained tissue). No pretreatment. e) Non pretreated membrane which mostly consists of a fibrovascular tissue architecture. No immunoreactivity (negative control). Without primary antibody (Anti Hsp70, magnification 20 x). The surrounding pink staining reaction is an artefact (arrow). f) Immunoreactivity to anti-HSP70 antibody of an untreated CNV membrane (pink stained tissue).
