be incited to vague esterase and once in a while to chloroac-

etate esterase reactivity while losing terminal deoxynucleotidyl

transferase. Morphological examinations in these cases uncovered cy-

tological development following TPA treatment. By and large,

these progressions were likewise somewhat inducible by refined cells in

medium alone or with the expansion of dimethyl sulfoxide however not

to the degree that was exhibited by TPA. Our examinations

demonstrated that MCS-2 is an awesome, explicit marker of intense

nonlymphocytic leukemia. A potential use for TPA to help in the

subclassification of patients with AUL is additionally recommended.


TPA4 has been appeared to advance the separation of numerous

cell types in vitro (1). Its impacts have been exhibited on

human lymphocytes (14), hematopoietic cells (2, 38), leukemic

cells (5, 9,19, 41), and cell lines (11, 22, 27, 28, 35, 37, 42). The

promyelocytic cell line HL-60 has been utilized widely to

exhibit both utilitarian and morphological changes asso-

Science meeting in Chicago (10). This work was bolstered by Grants CA-17034

Research Fund.

'Present location: Department of Immunology, Kurume University, School of

Drug, Kurume. Fukuoka 830, Japan. 4The shortenings utilized are: TPA, 12-O-tetradecanoylphorbol-13-acetic acid derivation; AUL,

intense undifferentiated leukemia; ALL, intense lymphocytic leukemia; AML, intense

myelocytic leukemia; AMOL, intense monoblastic leukemia; AMML, intense myelo

monocytic leukemia; AMEL, intense megakaryocytic leukemia; AEL, intense erythroid

leukemia; ANLL, intense nonlymphocytic leukemia; NSE, vague esterase; CAE,

chloroacetate esterase; TdT, terminal deoxynucleotidyl transferase; DMSO, di

methyl sulfoxide; FBS, fetal ox-like serum; PWM, pokeweed mitogen; PHA, phy-

tohemagglutinin; Con A. concanavalm A; Slg. surface immunoglobu

ciated with TPA acceptance. A portion of these modifications incorporate the

acceptance of NSE (35, 37), a marker of monocytic heredity (45),

joined by lost CAE (35), a marker of myelocytic

heredity, expanded phagocytosis (13, 35), and morphological

changes, for example, an indented core (36, 37), the entirety of which

show development towards a macrophage-like cell. Other cell

lines have likewise been utilized to show this differentiative

potential. Koeffler ef a/. (20) announced that myeloblastic-promye-

locytic cell lines (HL-60, ML-3, KG-1, and KG-1 clones 1, 2, and

3) could be incited to macrophage attributes, while early

myeloid impact cells (KG-1 an and K562) proved unable. Papayannopou-

lou ef a/. (31) found that TPA restrains globin combination in the

human erythroleukemia cell line while prompting morphological,

useful and biochemical changes trademark for large scale

phage-like cells. Pegoraro ef a/. (32) indicated that crisp cells from

AML and AMML uncovered changes after TPA treatment comparative

to those revealed for HL-60 and KG-1 lines. Likewise, Onta ef al.

(30) and Polliack ef al. (33) found that crisp leukemic cells from

patients with AML, however not ALL, have gotten follower after

momentary hatching with TPA. Since TPA has been found

to conquer the separation square average of leukemias, we

have utilized this compound to incite leukemic impacts to express

a myelomonocytic phenotype as characterized by monoclonal antibod

ies and cytochemical markers in 3 instances of AUL.
