Counting keratinocyte cells

 

 

Abstract--Algorithm is designed to identify the skin cells inside the skin surface layer excluding the loose cells.

 

(1) Staining method: Immunohistochemistry 
(2) Metric size of image: 180um  x 130um
(3) Cell type: Keratinocyte
(4) Positive staining cell numbers:
    (a) PD (Pyrimidine Dimer) staining:   untreated---none;
                         upon UVB exposure---induced;
                                 UVB exposure + lycopene treatment---downregulated(assumed)
     (b) PCNA (proliferating cell nuclear antigen)staining:   untreated---exist;                         

upon UVB exposure---downregulated;
                    UVB exposure + lycopene treatment---restored(assumed) 

 

Results: Sampled images are given bellow in pairs, one original and the other showing the image with the identified skin layer cells marked with bright crosses.
